I've owned a TiVo Series 2 80GB for about a year now. I love it. "Tivo is Mother. TiVo is Father."

Last month Comcast released the Motorola 6412 dual-tuner High Definition DVR. Grabbed one of them and am now enjoying being able to record "Lost" and "Smallville" at the same time in High Definition (used to TiVo "Lost" in standard definition and watch "Smallville" live). I am slso happy to be able to go to bed at 10pm after "The West Wing", secure in the knowledge that "Law and Order" is being recorded in HD.

That being said, I am still keeping the TiVo. The user interface for TiVo is miles ahead of the Microsoft one the 6412 uses. It is much easier to maintain and work with TiVo's Season Pass. Also, TiVo has a better analog-to-digital converter then the 6412 (the 6412's digital-to-digital compressor is pretty flawless. HD looks great, as does digital SD).

The 6412's big advantage - and it is huge to me - is dual High Definition-capable tuners. While we do not get CBS in HD over cable in Seattle (and probably never will with the whizzing match between Comcast and Cox), being able to record two HD (or one HD and one SD or two SD) channels simultaneously is a godsend when you have two shows at the same time.

But TiVo is much easier to work with.
