| Nvidia driver: 8774. B/W OSD w/ audio stuttering during OSD. Turning off "extra audio buffering" reduced audio buffer underruns. Not using NvAGP (enabling it made my CPU 90%+). Other than OSD problems, XvMC works great!

No audio buffer underruns with and without "extra audio buffering". I have to enable the "interleaved Normal" mode while watching tv to watch it perfectly. "Auto(E)" doesnt recognize the tv input as interleaved.

|Have to disable OpenGL vsync to handle 60fps progressive or 30fps interlaced (w/ bob deinterlacing) content. OpenGL vsync works fine with 24/30fps playback. OpenGL vsync with 60fps playback causes stuttering w/ prebuffering pauses, but only when OSD is not displayed - seems like a bug?

| Very smooth playback with XvMC. Stutters a little without XvMC. Didn't get Chromakey hack working. NOTE: I had 'Option "NvAGP" "3"' in my Xorg.conf, which caused the machine to crash when exiting from the EPG. (running Edgy Eft, on kernel 2.6.17-10-generic). Also had to set vsync to blank in nvidia-settings, for a smooth playback.
