Here are the potential problem areas.
A 2 gig P4 isn't enough to playback HD without some kind of MPEG2
acceleration, provided you are receiving MPEG2 streams. Without
hardware assist, generally one needs about 3 ghz or better to playback
And per the Wiki, XvMC doesn't work with ATI cards.
Assuming the XvMC situation has not changed, I would suggest either
getting a faster CPU or get a NVidia based card, which do support XvMC.
I'm sure that I'll be corrected if I'm wrong on these ideas. :-)
