There is no hardware decoder. The GF4 provides some help, but it is far 
from full-out decode. And I'm not sure if Daniel was running with XvMC 
support compiled in or not. I assume not, because I've heard that with 
XvMC support compiled in, you might actually be able to watch on a 
1.8GHz P4 or Athlon XP ~2000 without many problems, but it doesn't look 
as good as leaving XvMC off.

Daniel, was that 85% cpu running in Xine-HD, or in Myth? I've heard of 
a 3GHz HT P4 sitting at 70% when playing back in Myth with all the 
goodies enabled, so 85% on an Athlon XP 2800 doesn't surprise me at 
all. That's why I have a 3200 in my machine (for when I finally get my 
pcHDTV card out again)...
