No tuners found Back to top

Check to make sure that the HDHomeRun has a good network connection, as indicated by the

network LED on the device being solid green. For first/second generation HDHomeRun devices

(HDHR-US, HDHR-T1-US, HDHR-EU), the network LED is the leftmost of the ones in the

window. For HDHR3-US, HDHR3-CC, and HDHR4-2US, the network LED is the furthest left

LED. For HDTC-2US, the network LED is the furthest left LED. For HDTC-2US, the network

LED is at the bottom of the network port.

If the LED is blinking red (HDTC-2US) or solid red (other devices), this indicates that the device

does not have a network connection. Try a different network cable and port on your

switch/router.

If the LED is blinking green, this indicates that the device has a network connection, but has not

received an IP address via DHCP. If connected to your main network, check to make sure that

your router is powered on and has its DHCP server enabled. If the router has any access

control/allowed devices/MAC filtering function, either the HDHomeRun needs to be on the

allowed list, or this function should be disabled. If the HDHomeRun is directly connected to the

network interface on your computer, the interface should be set to a static IP in the 169.254.x.y

range (for example, 169.254.1.9) with a subnet mask of 255.255.0.0

If the network LED is solid green, then the HDHomeRun has an address. If your PC is using a

wireless connection, make sure that you are on the primary network and not a guest network

(guest networks typically block access to local devices on the network). If you are on the main

wireless network, please instead try a wired connection. If the wired connection works but

wireless does not, then the most likely cause is your router blocking certain kinds of network

traffic. Check the router’s configuration for anything with the word broadcast in it, or anything

like wireless partition/isolation/segmentation, and try toggling those options. If you are on a

wired connection and it is still not discovered, if you have the PC configured to use a static IP

address, check to make sure that the subnet mask entered exactly matches what the router is

assigning via DHCP. Any mismatch, no matter how small, can prevent discovery of the device

from working. If your PC has any VPN software installed, make sure you are not connected to

the VPN, and make sure any firewall the VPN may contain is disabled.

HDHomeRun QuickTV - channels not present in list, or channel scan required

message Back to top

The channel list in QuickTV is based on the channel names entered in HDHomeRun Setup. If a

channel does not have a name entered, it will not show in the list. If no channels have names

entered, it will report that a channel scan is required. Simply go into HDHomeRun Setup and

make sure all the channels that you want to access have names entered, and if you want,

numbers.

HDHomeRun app - no audio on Windows 7 Back to top

The audio decoder included with Windows 7 has limited functionality when used outside of

Windows Media Center and Windows Media Player. The HDHomeRun app will utilize decoders

from VLC if it is installed on the PC, and that typically provides better results.

HDHomeRun app - no video on Windows 8 Back to top

Windows 8 does not include an MPEG2 video decoder, which is needed in order to see TV. You

either need to add Windows Media Center, which includes Microsoft’s decoder, or else install a

separate decoder. The app will use any MPEG2 decoders installed on the system, including those

provided by VLC.

HDHomeRun app (Win7/8.1) - video freezes on first frame Back to top

This is typically caused by one of two programs installed on the PC. Either the ffdshow audio

decoder, or DirectVobSub. If ffdshow is installed, go into the Audio decoder configuration

program (search for it on the Start menu/screen), click on Mixer on the left side, set Output

speakers configuration to 2/0/0 – stereo, then check the box next to Mixer on the left side, and

click OK. Restart QuickTV and see if it plays normally.

If DirectVobSub is installed, it will show up in the system tray or hidden icons area (in the

bottom corner next to the clock) as an icon labeled VobSub or DirectVobSub. Double click on

that, locate the Loading option, set to Do not load and click OK. Restart QuickTV and try again.

HDHomeRun app (Win7/8.1) - does not find DVR Back to top

The HDHomeRun app for Windows 7/8.1 does not support the DVR. On these platforms, use

Kodi to access the DVR. See http://my.hdhomerun.com/instructions/kodi/

HDHomeRun app (Win10) - does not find DVR Back to top

Please right click on the Start menu icon and select Windows PowerShell (Admin) or Command

Prompt (Admin). Run the following command:

CheckNetIsolation LoopbackExempt -a -n=”ef712ba7.hdhomerundvr_23nna27hyxhag”

You should get a response of “OK.” Open the app and check to see if you can then access the

DVR.

HDHomeRun Setup - Discovery Error 4001 Back to top

This indicates that there is a hardware issue with your device. Please open a trouble ticket so that

it can be replaced.

Back to top

During installation of the HDHomeRun software, you may receive an error stating “Service

‘HDHomeRun Service’ (HDHomeRun Service) failed to start. Verify that you have sufficient

privileges to start system services.”

This error is due to the SSDP Discovery service being disabled. To re-enable the service:

1. Click the Start menu, right click on Computer and choose Manage

2. Expand Services and Applications and click on Services

3. Locate SSDP Discovery in the list, right click on it, and select Properties

Once the service is enabled, run the installation program again.

HDHomeRun PRIME - Hardware & Basic Configuration

Leftmost LED on HDHomeRun is blinking green Back to top

This indicates that the HDHomeRun has a network connection but is not getting an IP address

from your router. Check to make sure that the DHCP function is enabled on your router, and that

either the allowed devices/access control/MAC filtering function on the router is disabled, or that

the HDHomeRun is on the allowed list.

Second from left LED on HDHomeRun is blinking green Back to top

This indicates that either the CableCARD is not initializing correctly, or is not getting an out of

band connection. Check to make sure that signal is present on the cable line you are using. Also

check the CableCARD Menu screen on the HDHomeRun PRIME’s web page and make sure that

the card information is present, and that the Card Authentication shows “success”. If both of

these are true, please do the following:

1. Go into the Advanced tab in HDHomeRun Setup, and check the Send diagnostic

information to Silicondust support box

2. Unplug the power cord from the HDHomeRun, count to ten, and plug it back in

3. After the HDHomeRun finishes initializing, remove the CableCARD

4. On the Tuners tab in HDHomeRun Setup, set one tuner to Digital Cable

5. On the Digital Cable tab, run a channel scan

6. After the scan finishes, reinsert the card and set the tuner back to CableCARD

7. Open a support ticket. Make sure to include the 8 digit device ID for your HDHomeRun

so our support personnel can review your diagnostic data. Note that you do not need to

send any files, all information is sent automatically once the box is checked.

Channel scan stops immediately with no channels found Back to top

Page 4: HDHomeRun Windows software

First, verify that the second LED from the left on the HDHomeRun is solid green. If not, follow

the above steps.

If you are using a Motorola CableCARD, go to the web page for your HDHomeRun device

(click on one of the tuner numbers on the Tuners tab in HDHomeRun Setup), then click on

CableCARD Menu, then Network Setup. Look for the VCTID, and VCT or VCT Rcvd entries.

If the VCTID is 0, this indicates that the cable provider has not yet initialized the CableCARD.

Contact the provider and ask them to perform a “cold init” or “DAC init” on the card.

If the VCTID is something other than 0 but VCT/VCT Rcvd is 0, this indicates that the

CableCARD has been configured incorrectly by the cable provider and is not receiving a channel

lineup as a result. The provider will typically need to change the hub or headend setting

associated with the card in their system. In the case of Comcast, this is not something that can be

performed by a phone representative. Either the phone representative needs to escalate the issue

to the local operations/warehouse/addressability people, or a tech needs to visit, and make a call

to those same people and have them correct the setting.

If the VCTID is something other than 0 and VCT/VCT Rcvd is also non-zero, then please send

us diagnostic information and open a trouble ticket:

1. Go into the Advanced tab in HDHomeRun Setup, and check the Send diagnostic

information to Silicondust support box

2. Unplug the power cord from the HDHomeRun, count to ten, and plug it back in

3. On the CableCARD tab, attempt to run a channel scan

4. Open a support ticket. Make sure to include the 8 digit device ID for your HDHomeRun

so our support personnel can review your diagnostic data. Note that you do not need to

send any files, all information is sent automatically once the box is checked.

Some but not all expected channels are found in a scan Back to top

Go to the web page for your HDHomeRun device (click on one of the tuner numbers on the

Tuners tab in HDHomeRun Setup), then click on CableCARD Menu. Make sure that

CableCARD Validation shows success. If it shows none, contact your cable provider, as the card

must be validated in order for copy-protected channels to be received.

If you are using a cable provider that uses switched digital video technology (including but not

limited to TWC, Brighthouse, Charter, and Cox), check with your provider to determine if a

tuning adapter is needed for CableCARD devices in your area. If so, make sure that you have

one and that it is connected. Check the Tuning Resolver Menu on your HDHomeRun PRIME’s

web page and make sure that it shows success, success, succes, and ready, indicating that the TA

is functional.

If you have a tuning adapter or are in an area or using a provider where one is not needed, and

the CableCARD is validated, please do the following:

Page 5: HDHomeRun Windows software

1. Go into the Advanced tab in HDHomeRun Setup, and check the Send diagnostic

information to Silicondust support box

2. Unplug the power cord from the HDHomeRun, count to ten, and plug it back in

3. On the CableCARD tab, run a channel scan

4. Open a support ticket. Make sure to include the 8 digit device ID for your HDHomeRun

so our support personnel can review your diagnostic data. Note that you do not need to

send any files, all information is sent automatically once the box is checked. Also include

a few channel numbers that you should be receiving but are not.

CableCARD Validation shows none, but some encrypted channels are accessible

Back to top

Card validation is entirely a function of the cable provider sending the correct message to the

CableCARD. The most common cause of problems is simply typing in the wrong numbers. Ask

the support representatives from your provider to read back the numbers entered in their system,

and make sure they match what you see.

If you are using a Motorola CableCARD, both the Host ID and Data numbers must be entered.

One or more of the other numbers may also be needed, though it will vary by provider. You may

want to refresh the page after they perform their actions and make sure that the Data number

remains the same. If it did change, then this indicates that your provider unpaired or reset the

CableCARD. This is not necessarily incorrect, but if they do this, you must provide the new Data

number before they try to validate again, or it will fail.

If you are using a Cisco CableCARD, the host ID number must be entered into the cable

provider’s system. One or more of the other numbers may also be needed, depending on the

provider.

Unable to access encrypted channels - Cisco CableCARD Back to top

Go to the web page for your HDHomeRun device (click on one of the tuner numbers on the

Tuners tab in HDHomeRun Setup), then click on CableCARD Menu. Make sure that

CableCARD Validation shows success. If it shows none, contact your cable provider, as the card

must be validated in order for copy-protected channels to be received.

If validation is showing success, then go back to the main page for the device, click on Status

Menu, then Log. You should see a log entry for the channel attempting to be tuned (the timezone

listed will be UTC, so subtract the appropriate number of hours to reach your local time – during

DST, 4 hours for Eastern and 7 for Pacific; during standard time, 5 hours for Eastern and 8 hours

for Pacific). If you see a line that says “subscribed”, then 5 seconds later a line that says “not-

subscribed”, this indicates that the card has not been staged correctly by the cable provider. In

many cases this can be resolved by having them perform a hard reset on the CableCARD. In

other cases, they need to remove the card from the account, reassign to inventory, then pull it

back out, readd to the account, and set it up from scratch.

Page 6: HDHomeRun Windows software

If the card is validated and the log shows just a single line that says not-subscribed, then the card

does not have the correct channel packages added to it. Contact your cable provider.

Leftmost LED on HDHomeRun is solid red Back to top

This indicates that the HDHomeRun does not have a network connection. Please try a different

network cable and port on your switch/router. If the issue persists, please open a trouble ticket.

Middle of 3 tuner LEDs is blinking, no other LEDs lit Back to top

This indicates a hardware issue with your HDHomeRun. Please open a support ticket.

CableCARD information is missing Back to top

Go to the web page for your HDHomeRun device (click on one of the tuner numbers on the

Tuners tab in HDHomeRun Setup), then click on CableCARD Menu. If the Card Manufacturer,

Card Authentication, and Card Validation lines all show as none, this indicates that the

CableCARD is not in a usable state. The most common cause of this would be if the card is not

inserted correctly. The card should be inserted with the colored label facing up, and the 68 pin

connector going in to the HDHomeRun. It will require a slight amount of force to seat the card in

the socket. Approximately half an inch of the CableCARD will remain outside of the

HDHomeRun when fully inserted.

If the card information is still missing and you have verified that the card is inserted correctly, try

another CableCARD.

161-0 message displayed in logs Back to top

The logs may show 2 lines like this, particularly when working with the cable provider to get the

CableCARD set up:

CableCARD: message: A technical problem is preventing you from receiving all the cable

services at this time. Please call your cable operator and report error code 161-0 to have this

problem resolved.

CableCARD: card indicated fatal error or firmware upgrade (ccio_detect:xxx)

CableCARD: technical error 0 (ccio_detect:215)

This is not necessarily an error. This is simply how the CableCARD asks for itself to be

rebooted, which is often necessary for changes made by the cable provider to take effect. You do

not need to call your cable provider, as it is normal to see this when they are working with the

card, or if a firmware update is done to the card.

invalid session 0xDEAD message displayed in logs Back to top

When using a Cisco CableCARD, you may see a message in the logs saying:

Page 7: HDHomeRun Windows software

invalid session 0xDEAD (cchost_session:x)

This is completely normal. Cisco cards are designed to do this when they first boot up. It does

not indicate any kind of problem. Simply disregard the message.

HDHomeRun CONNECT/4DC - Hardware &

No/few channels found in channel scan Back to top

If you are using cable, verify that unencrypted digital channels are present on the line you are

using. Many larger cable providers, including Comcast, RCN, TWC, Charter, Brighthouse, and

Cablevision, have begun encrypting all channels they carry. HDHomeRun CONNECT would not

be usable with these providers – you would need to utilize an antenna in order to receive over the

air broadcasts (if available), or instead use HDHomeRun PRIME along with a CableCARD from

the provider.

If you are using an antenna, verify that signals are present on the same cable using another

device, if possible. If you have an amplifier on the line, try removing it in order to make sure that

you are not overloading the tuners.

If you are using the HDHR-EU, HDHR3-EU, or HDHR3-4DC with a DVB-C signal source,

verify that you have the correct modulation settings entered on the DVB-C tab in HDHomeRun

Setup.

If you need further assistance, please open a support ticket:

1. Go into the Advanced tab in HDHomeRun Setup, and check the Send diagnostic

information to Silicondust support box

2. Unplug the power cord from the HDHomeRun, count to ten, and plug it back in

3. On the Digital Cable or Digital Antenna tab (whichever is appropriate), run a channel

scan

Broadcast channel works in QuickTV but no signal in WMC Back to top

Situation: when using an HDHomeRun Connect/Extend connected to an antenna to receive over

the air broadcasts in the US, all channels play in QuickTV, and most play in WMC, but a couple

give a no signal error. This may also appear as channels that work in Live TV mode but fail

when recording, or vice versa. Note: this section only applies to broadcast TV, not cable.

Stations that are known to have had this issue in the past (others may also be affected):

WLS and WBBM Chicago

WESH Orlando

KGO/KTVU San Francisco

KIRO/KCPQ Seattle

Page 9: HDHomeRun Windows software

WOIO Cleveland

KOPB Portland

Every major Salt Lake City station

(KUTV/KTVX/KSL/KUED/KUEN/KBYU/KSTU/KUPX/KJZZ/KUCW)

WTAE Pittsburgh

WMVS Milwaukee

KVOA/KGUN/KOLD Tucson

In short, this issue occurs because these stations are/were transmitting on more than one channel

in your region, either because of a channel change, or because of translator stations that are used

to serve nearby towns that can’t receive the primary transmission due to terrain. WMC isn’t

smart enough to know which one(s) you can receive, so it adds both, then guesses which one to

use. If it guesses wrong, the channel will not work.

To correct the situation, go into Tasks > Settings > TV > Guide > Edit Channels > affected

channel > Edit Sources. Open HDHomeRun Setup alongside this. In WMC, you’ll see all the

different sources you have for each channel. If you mouse over the different sources, it will show

you at the bottom the channel number it is on. Disregarding the parts after the . and -, compare

this to the channel listed in the Tune column for that channel in HDHomeRun Setup, and

uncheck the ones that don’t match. For example, for KTVUDT, there will be entries in WMC

that say 44.1 and 48.1. For most people, HDHomeRun Setup will list 44-3 for that channel. This

means that 44.1 will be left enabled, and 48.1 needs to be disabled. Repeat for any other affected

channels.

These steps will need to be repeated on any other PCs you’re using WMC in, and in the future if

you ever go through the TV setup wizard in Windows Media Center again.

Video Error: Files needed to display video are not installed Back to top

This error is often caused by using a digital audio output on the PC (HDMI, S/PDIF, coax) and

WMC being unable to reserve it for exclusive use in order to pass surround-sound audio. If you

are not using a receiver to process surround-sound, this can be disabled by enabling the auto-

volume feature in WMC. Go into Tasks > Settings > TV > Audio and check Auto volume. Save,

and exit and reopen WMC. It should now play normally.

No channels found during scan (clear QAM/DVB-T/DVB-C or no audio/video

(ATSC/CableCARD) in WMC Back to top

This usually indicates that a firewall is blocking the stream from the HDHomeRun. Please check

your firewall configuration and make sure that the HDHomeRun programs and the Windows

Media Center Receiver Service have full access under all profiles. If issues persist, try

completely disabling the firewall.

If you are are using your HDHomeRun with WMC in a Domain environment, you may need to

go into the Advanced Firewall Configuration and change the Inbound connections behavior to

Block rather than Block all connections.

Page 10: HDHomeRun Windows software

This indicates that WMC is not detecting the presence of a protected output path to your screen.

There are several possible reasons for this:

If you are running WMC inside a VM of any kind, including VMWare, VirtualBox, Parallels, or

Hyper-V (including the Hyper-V host), you will not be able to access protected content on the

PC.

If your video card is not HDCP-compliant, you will not be able to access protected content on

the PC. Almost all modern video cards are HDCP-compliant, but some cards designed for

workstation use (e.g. FireGL/FirePro) may not.

If your display is not HDCP-compliant, you will not be able to access protected content on the

PC. Nearly every TV since 2006 and nearly every computer monitor since 2008 does, but verify

that support is listed in the manual.

If you are using any type of connection between the display and PC other than DVI or HDMI,

you may encounter problems. DisplayPort is not accepted by Windows Media Center as a valid

connection type, and cannot be used. This includes the embedded DisplayPort connection used in

many tablets and some laptops for the internal connection between the mainboard and the

display.

If you have any type of remote access software on the PC such as TeamViewer, VNC, Remote

Administrator, GoToMyPC, PCAnywhere, or LogMeIn, these programs may intercept the video

data, breaking the protected path. Remove them.

If you have installed any codec packs such as Shark007 that modify or disable Microsoft

components, these can cause problems for WMC. If you choose to install such programs, make

sure to disable any options that would have them modify any Microsoft DirectShow or Media

Foundation components (typically there will be a checkbox for this). If you have used any other

programs such as Win7DSFilterTweaker to disable any components, undo those changes.

Video appears washed out/brightness levels are incorrect Back to top

Windows Media Center’s default settings are intended for use with older TVs that are designed

to accept a different range of brightness levels than PC displays. Newer TVs, however, will

detect when they are connected to a PC, and will configure themselves to expect PC levels. This

mismatch causes WMC to send the very darkest parts of the screen at a brighter level than they

should be, and the very brightest parts of the screen at a darker level than they should be. This

makes the image appear washed out. There is a registry fix available at

http://www.hack7mc.com/2009/06/fixing-media-centers-poor-black-levels.html that will correct

these levels.

Service Unavailable/No Signal message appears for all channels Back to top

This typically indicates that a firewall is blocking the stream from the HDHomeRun. You will

need to check the program control in your firewall and give the Windows Media Center Receiver

Service (c:\windows\ehome\ehrecvr.exe) full network access. For third-party firewalls, refer to

the program’s documentation for instructions on allowing a program through the firewall. For the

Windows Firewall:

1. Open Control Panel

2. Click System and Security

3. Click Allow a program through Windows Firewall

4. Click Change settings

5. If Windows Media Center Receiver Service is present in the list, check all boxes for it,

then click OK. If Windows Media Center Receiver Service is not listed:

6. Click Allow another app…

7. Click Browse

8. Navigate to c:\Windows\ehome, select ehrecvr (not ehrec), and click Open

9. Click Add

10. Windows Media Center Receiver should now be present. Check all boxes for it.

11. Click OK

Check your firewall configuration and make sure that the NextPVR, NRecord, and NDigitalHost

programs have full network access.

For HDHomeRun Connect/Extend/4DC Make sure that the Main Application in HDHomeRun

Setup is set to Other:ATSC/QAM or Other:DVB-T/DVB-C while you are running the scan. It

can be changed back to the standard NextPVR option once the scan is finished.

For HDHomeRun PRIME, make sure that you are running a firmware version of 20130328 or

newer and that you have completed a channel scan in HDHomeRun Setup.

No video or audio Back to top

Check your firewall configuration and make sure that the NextPVR, NRecord, and NDigitalHost

programs have full network access.

In the codec configuration area in NextPVR, make sure that you have selected decoders for

MPEG2, H.264, and AC3.

DLNA/UPnP

HDHomeRun not found Back to top

Make sure that you are using an HDHomeRun that supports DLNA/UPnP:

HDHomeRun PRIME (HDHR3-CC)

HDHomeRun Extend (HDTC-2US)

HDHomeRun Connect (HDHR4-2US)

HDHomeRun 4DC (HDH3-4DC)

Earlier devices do not support DLNA/UPnP and will not be accessible.

If you are using Windows software, make sure that you do not receive an error about UPnP when

opening the HDHomeRun Setup program.

If the device you are accessing from is using a wireless connection, try a wired connection.

XBMC - no audio/video Back to top

Make sure that you are using XBMC version 12.3 or later.

Make sure that you are not attempting to access a channel with [drm] in the name (HDHomeRun

PRIME only).

Page 15: HDHomeRun Windows software

If you are using a Raspberry Pi, make sure that you have purchased and activated MPEG2 codec

support.

VLC - no audio/video Back to top

Make sure that you are not attempting to access a channel with [drm] in the name (HDHomeRun

PRIME only).

Try a different version of VLC. Due to the ever-changing nature of VLC, some versions have

bugs with device discovery or playback. On Windows, try both 32 and 64 bit versions.

No channels listed Back to top

Make sure that you have completed a channel scan in HDHomeRun Setup or on the web page for

the HDHomeRun.
