I had a similar problem with the GeForce FX 5200 Ultra using XvMC. (I am
running Debian Testing).
I tried many things and was constantly frustrated by the fact that Myth
would only play HD in a horribly choppy manner, yet Mplayer seemed to work.
Turned out that MPlayer was just better at dropping frames: neither were
using XvMC properly.
What made it work was having /etc/X11/XvMCConfig contain the line:
Suddenly, everything worked. Not perfectly (There are some weird offsets
that I have not looked into), but it worked and was watchable. Which is
nice, as I only have a 1.1GHz Athlon.
Check your /etc/X11/XvMCConfig (or distribution equivalent).
Hope this helps.
