Check 1 - Record vs playback.
The first thing to determine is if the recording itself contains a glitch, or if the problem was
caused by playback. A misconfiguration of the PVR application/codec or a complicated
onscreen display can cause glitches that are only seen on playback through the PVR
application.
Make a recording of the problem channel in your DVR application (or use an existing
recording that shows the symptom).
Try playing the same file in VLC. To do this you will need to navigate your hard drive and
locate where your PVR application stores recordings.
If VLC plays the recording without error then it suggests the problem is with the PVR
software or MPEG2 codec installed in Windows or with the video drivers. See symptom
below.
If VLC shows the same symptom then the problem is in the recording. Proceed to check 2 -
signal strength and signal quality.
Check 2 - Signal Strength and Signal Quality.
● In your DVR application go into live TV mode. Choose a problem channel.
● Use the HDHomeRun software to determine Signal Strength and Signal Quality
○ Windows users: Open HDHomeRun Config (GUI). Click on one of the tuner icons to
select the tuner.
○ Other OS: Use the command: (Fill in the correct Device ID and tuner number)
hdhomerun_config <device id> get /tuner<n>/status
Signal strength will be reported as ss, Signal Quality will be reported as snq.
● Digital Antenna:
○ Check that the signal strength is above 60% minimum (75% recommended).
○ Check that the signal quality is above 50% minimum.
○ Check that the symbol quality is 100%.
● Digital Cable:
○ Check that the signal strength is above 80% minimum (90% recommended).
○ Check that the signal quality is above 50% minimum.
○ Check that the symbol quality is 100%.
Check 3 - Logged tech support (Windows).
Occasional reception issues or network issues can be logged and checked by Silicondust
support.
Run HDHomeRun Setup and go to the support tab. Enable debug logging (“Enable
connection to Silicondust support server”). Switch back to the system tab and click rescan.
● Live TV problems - stay on a problem channel for at least 5 minutes. File a trouble
ticket and include the time you tuned to that channel.
● Occasional problems - when you see a new recording with an error please file a
trouble ticket. Include the time the recording was made and how often the video
problem was seen in the recording.
