I figured out a work-around. If I use "Seperate video modes for GUI and TV
playback" so that I drop my resolution from 1920x1080 to 720x480 for playing SD
recordings then I can play a SD recording with XvMC without any problems.
Something about the combination of XvMC and forcing myth to up the resolution
was causing the prebuffering pauses.
