If TV Guide would work, CableCard could be great. My wishes are to put a TV in my master bedroom. I don't need, or have room for a cable box, and I want HDTV. I WANT to use the speakers inside the cabinet for most of my day-to-day (or mostly nightime) viewing. Yes, I have in-wall speakers and I can watch and use my HD-DVR cable box as well, but I only want to do that when I have to, not all the time.
CableCard, at the very least, is a good idea that is headed in the right direction I think. Just 10 billion more standards to write before every manufacturer can really screw it up.
