Hello all,
Yesterday I setup my new box with MythDora 12.23.
Now When watching LiveTV using any of the vdpau profiles (slim or
normal) I get artefacts every 20-30 seconds. This is on HD and SD.
My Hardware is a nVidia GeForce 8200 IGP.
I already tried to add "vdpaubuffersize=32" to the filter options, as
mentioned somewhere in the mythtv/vdpau-wiki, but this did not help.
"Extra Audio Buffering" and "OpenGL as timebase" are set
Here's my xorg.conf:

I'm using the nvidia kmod that came with the MythDora installation.
This is what is in my mythfrontend.log:

Does anybody know anything about this or how to resolve that?
