[mythtv-users] Playback problem

The last few weeks i have had a problem with playback. I have used VDPAU
since about 1½ year without any problems. But recently when watching
recordings i get a lot of pixelation(or what it is called) when there is a
scene change or fast moving scenes when there is a lot of movement on the
screen. If i switch to OpenGL instead of VDPAU the problems go away.

But then i get another problem. With OpenGL i cant watch LiveTV, i get a
lot of:

2012-03-30 21:07:38.022078 N [8320/8320] CoreContext mythplayer.cpp:2079
(PrebufferEnoughFrames) - Player(4): Waited 102ms for video buffers
AUUUUUUUUuUuLAAAAAAAAAAAAAAAAAAP

And i get a little paus every 2-3 second, impossible to watch LiveTV. But
to get it even more strange, VDPAU seems to work fine with LiveTV.

LiveTV: VDPAU = Good, OpenGL= Bad
Recordings: VDPAU = Bad , OpenGL= Good

I have a Intel(R) Core(TM)2 Duo CPU E8200  @ 2.66GHz, and about 15-22% cpu
utilization when running OpenGL, so i should have enough power, and since
it works fine with recordings...

If someone is interested to help me i would be happy to supply better log
files, but i dont know what options to enable that would be helpful.
