Which video card do you have?
I have a Sempron 3000, which should be enough, and my TV runs at 720p,
so I guess I should be able to show HD. But it fails miserably with
prebuffering pauses and the CPU is pegged > 98%, so something is wrong.
I have another system with an Athlon XP 2000+, which shows HD content
just fine at 800x600 on TV out with 65% CPU.
The big difference between the two machines is that the Sempron has an
nVidia 6200 whereas the Athlon has an nVidia 5200... ISTR reading that
the 5200 is actually better at HD playback? Can anyone confirm that?
