Maybe some of the changes that Kevin mentioned have helped this.. My system is: Gentoo x86-64, kernel 2.6.14, NVidia driver 7676, FX5200 video card, latest MythTV svn as of last night, HD3000 and FusionHDTV3 QAM cards.

Matt,
Today I finally got XvMC playback working, after trying lots of
different settings, drivers, etc. What finally got rid of stuttering
and slow playback for me was increasing the ringbuffer size. My
symptoms in the log were lots of "prebuffer pause" and "video ahead of
audio" messages (so probably not the same thing as Kevin's problem).
