[mythtv-users] Playback/TV display failing

[Stephen Tait]

Hmm. Bit of an odd problem.

Basically, TV playback is periodically failing. By this, I mean when I go 
to watch live TV, or play back a TV recording, I sometimes get a blank 
screen, although I can hear the sound playing back. This only seems to 
affect TV streams recorded from my PVR-250, since fullscreen video and DVD 
playback via Xine works fine. A reboot or X restart sorts it out. From 
memory, this only occurred after I switched from XFree86 to x.org. I've 
checked the obvious logs, but couldn't find anything that looked relevant. 
The streams are all recorded fine, since I can play them back in Myth 
(eventually) and from other machines.

FYI, my setup is as following:

Myth 0.15.1 (with XV support)
ivtv 0.19r3
nVidia 5336 (output via VGA to a bog standard CRT)
x.org 6.7r1
2.4.25

Anyone got any pointers as to what might be going wrong?

TIA!
