Can someone please cite the key features that make TiVo so much better than the Comcast offering? I currently use a Motorola 6412 that I lease from Comcast and I am nothing if not pleased with it. All the features work beautifully and I don't feel like I'm missing out on anything (once I programmed 30 second skip into the remote, that is). If I had to complain about anything it would be the recording capacity since it is only 120GB. All hackability and use of open-source software aside, what *user-level* features does TiVo have that the Motorola 6412 or 6208 boxen not have? What am I missing out on?
