One thing that no one has mentioned here is that progressive video  
from the HD-PVR cannot take advantage of dual core processors without  
CoreAVC (and appropriate patches). Because of the way the video is put  
together, all of the image processing happens on one core and any  
deinterlacing can happen on the other core if you record at 1080i. But  
if you're got 720p content, the second core is left unused - even with
