I don't have HDTV available here, but the folks over at pchdtv.com have 
been advocating fast CPU's for quite some time now (that reminds me, I'd 
better add a bit to the wiki about it). Their current spec indicates a 
1.2GHz Pentium or equivalent, and I'm assuming this is in conjunction with 
an accelerated GeForce4 or better.

Maybe you could build a Beowulf cluster of Xboxes to decode the HDTV ;)
