Comment(by Doug Goldstein <cardoe@…>):

 #7611 is probably a dup of this issue. I've got an ASRock ION 330 that
 experiences this exact same issue that is running Mythbuntu 9.10 with
 auto-builds of 0.22 fixes. I'm using the VDPAU Normal playback profile.
 Odd thing is my friend has the exact same machine with the exact same
 software, the only difference is that he's changed his playback profile to
 a custom one and it works every time for him.

 I'll work through the list of items to try myself.

 * I'm using 185.18.36.
 * Using 0.22 fixes. I know it happened with the mythbuntu 0.22 deb based
 off of r22840.
 * Just using plain Mythbuntu that starts right into Mythfrontend and
 that's it.
 * Using Mythbuntu (widescreen) theme, using OpenGL painter.
 * Composite extension is explicitly disabled in xorg.conf
 * I've tried with and without OpenGL Vsync.
 * I've got 2GB of RAM with 256mb allocated to the video chipset.
 * I never leave Myth at the Watch Recordings screen, I always exit out to
 the main menu.

 The problem only occurs when the frontend is left idle or running for a
 while. For example, I use it at night after work and everything I try to
 playback works just fine. It won't be used during dinner and then after
 dinner it still works. But then the next day if I come home during lunch
 and try it, it doesn't work. That's roughly 12 hours after I stopped
 watching TV the night before.

 I would suspect its a memory leak overtime or the CPU stepping down its
 clock and then not able to provide data fast enough.
