Thanks Mitch! This page http://www.mythtv.org/wiki/index.php/XvMC seems to 
show a 1GHz Thunderbird playing just fine using a GeForce 4MX. I'll look 
into upgrading the video card, but my machine should also take a 2.8GHz P4 
or even a 3.06GHz HT P4, but the latter are still pricey.

Seems like my 3Ti just won't cut it.

Excellent. Will try this tonight.

The page I linked to above also shows tips for smoother playback. NVAGP, 
bob and seperate video modes might help.
