I've had my TiVo for 3 years now, and I'm ready to buy a plasma HDTV. I know if I get a HD cable box, my TiVo won't record the HD channels. But my question is, how will the picture quality be for normal digital cable channels on my new television? Also, is there a way that I can enjoy the HD channels if I change channels through the cable box as opposed to the TiVo? Sorry if these are stupid questions - but any help would be muchly appreciated! I want to upgrade my tv and hopefully avoid getting rid of my loyal TiVo. Thanks!
