Mark,
If you subscribe to digital cable, Comcast offers Discovery Theater HD, ESPN-HD, and CSN-HD (if applicable), plus the local networks, which offer HDTV during primetime hours (and during sporting events). Comcast also offers HBO, Cinemax, Showtime, and Starz in HDTV if you subscribe to those packages.
Try the Comcast DVR and see how you like it. It records the original digital signal without modification, so recordings of digital and HDTV channels are identical to the original broadcast. If you can't stand the software on the Comcast DVR, you can always return it with no penalty or fee. Many have chosen to keep their Tivo for SD and use the Comcast DVR for live viewing and HD recording.
For future reference, questions on HDTV DVRs belong in the HDTV Recorders forum.
