black screen on some channels

[craigrs84]

This probably wasn't smart but I recently upgraded the following software all around the same time:
- Windows 10
- NextPVR latest version
- HDHomeRun latest version

Now I'm having issues with a few channels in NPVR; the problematic channels frequently load with a black screen and no audio. I'm not positive but I don't remember seeing this type of issue prior to upgrading my software.

For example, I was trying to watch Friends on CBS, channel 45 (virtual channel 44.2), I kept encountering issues. I ran a test found that roughly 75% of the time I'd encounter a black screen when trying to load the channel, other 25% the channel would load fine. I tried using HDHR View software multiple times and didn't encounter any issues loading the same channel, although I'm not sure if HDHR View uses the same protocols (BDA?) as NPVR.

I disabled transcoding on my HDHR and saw the same results with transcoding disabled. I'm not sure how to fix. I've attached my logs below from when I was trying to watch the broken Friends episode. Appreciate any help, thanks.

EDIT: The channel I tested with that was failing had a signal strength of 100%, signal quality of 98%, and symbol quality of 100%, according to the HDHR software.

If you record one of those channels, do you see a valid sized file on disk? can you play it in another player?

[craigrs84]

If I record for about 30 seconds it has a file size of 82KB. I assume the file should be larger than that.

I'm not able to play the file in NPVR, VLC, or the windows 10 video app.

I'd probably head to the SiliconDust config app, and check what it thinks is happening while you're recording or watching that channel. ie, signal locked, data rate etc.

Maybe try creating a c:\temp, and set the following registry settings:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\NPVR\LogTSFlow=1
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\NPVR\LogTSWriter=1

Then try watching that channel for like 20 seconds, then zip and attach the files that get created in c:\temp, along with the normal NextPVR logs.

here's what I got:

I added the registry values as strings, was that the correct data type? Or should they have been dwords?

Going to bed, will check back tomorrow, thanks for help

Sorry, yes they should be DWORD.

Sorry, yes they should be DWORD.

Ok, changed the registry entries to DWORDS, then restarted computer afterwards just in case. Updated log files here:

if you can spare time, can you confirm that these log files are what you needed? Thanks. Sorry for the bother.
