great, I'll have to turn off "Sync to VBlank" and test. Without OpenGL
Vsync I have to have Bob on for 1080i content, I'll have to see which
works out better. (ie least CPU usage).

Jesse, have you noticed XvMC stuttering during the OSD for HD content?
I've also noticed that with 720p if I pause and resume the playback
pauses after the OSD fades out unless I force it to dissapear, and
even then sometimes...
