Thanks, Kyle! On #5, yes, I meant the cpu cost of playback only. As I said, I'm really pleased to hear these answers. I plan to get a pcHDTV card before Big Brother comes along in July, but I don't plan to get an HDTV that soon. I'm hopeful that my processor will be able to handle HD playback, as that was the entire reason why I went with a high-powered P4.
