      Should'nt it be easier than that?  DVI/HDMI is all digital, no? 
Would it not be just question of reading the data then writing it to 
disk?  I have'nt seen a component HD set for sale at Costco/Worst 
Buy/Circuit City in a while now.

      Dish 942 receivers have HDMI while the 811 has DVI.  I think the 
old 921 did as well.  Dunno about DTV.  Probably a similar story.

      Seems a lot easier to me.  But then I'm not an electrical engineer.
