This is not my experience. With a discrete 9500 card, I have to ensure
that my Athlon 5050e doesn't clock at its slowest rate (1GHz) or else
VDPAU stutters. I have to keep it at the next lowest speed (1.8GHz)
for stutter-free playback. I still haven't gotten around to playing
with the new MythTV event system so that I can change the minimum
speed when playback starts and stops...
