I have a knoppmyth R5C7 setup. I have two TV cards, A PVR350 and PVR250.
Both tuners appear to be working fine. Randomly, when I try to watch a video or TV recordings, they show up as blue screens (sometimes black) and all I get is sound but no video.

This has happneed more frequently later. I have read some posts that make me think it could be something after I watch TV, or if you watch one video in mplayer then after that everything is messed up, but I am not really sure.

The preview when you have a TV playback show hightlighted works just fine. It's just when I got to actually watch it that I have problems.

I should probably mention I am using the PVR350's TV out also.

I can't find much in the logs either.

Here is lspci -v



Any help would be appreciated.

I can post any configuration, output or logs that are requeste, I just really don't know where to start.

I think you need to diagnose it a bit more:

1) Does it happen when playing videos, tv recordings or both?
2) Does it always happen every time with the same piece of media, or sometimes yes, sometimes no?
3) Are there any pieces which never have a problem?

The reason I ask is that I had a similar problem with random blank screens that only happened when playing videos through mplayer (and not tv recordings through the internal player). It went away when I recompiled mplayer (as part of a mythstream install).

I don't have a lot of time to troubleshoot tonight, but I can say:

1. It happens with TV playback
2. It happens with mpalyer playback. The first time, it was just sometimes, (not even just certain files, just randomly) . Since then, no playback of mplayer has worked.

I was thinking about rebooting to clearup memory or something, but that really doesn't fix the problem.

Have you tried switching back to the monitor output (ie not the 350)?

No, I haven't, because I don't have a monitor in that room. I would tend to think that the problem is driver related, but I have little to no data to show that.

I have an identical problem with an nVida chipset using VGA out.

I've got that same problem -- did you build mplayer manually (tar xf, ./configure, make, make install) or build it using apt-get?

I just used the stock mplayer included with knoppmyth. I could build from source, but figured I was start here with questions. After my last reboot it hasn't been happeneing as much. Go figure. My board is an Nvidia chipset also.

Yes manually using tar, make, make install. As I said I was doing a mythstream install from here:

When I tried it the script was failing, so I manually stepped through the steps in script. Oh, and I should mention it was R5B7, haven't got round to R5C7 yet.
