I must be lucky then.  I have an AMD 3500+ that runs at 1080i.  I rarely 
hit 75% on my CPU and do not suffer from any stutters on playback. I 
found that the key for me was:

1)  Find the proper modeline for your LCD or plasma.  It makes a huge 
difference in playback and CPU usage
2) Switch to a lightweight window manager.

Prior to my reinstall several months back I was running Ubuntu Breezy 
with a full blown Gnome install.  Had all sorts of problems with HD 
material.  I reinstalled using the server install for Dapper and 
installed Ratpoison as my window manager.  I compiled from source and my 
system has been rock solid for months.  Prior to that, it was hit or miss.
