The service that you're paying for is TV listings. I recently found out that with Comcast's box, you can only record by time and date. WTH? With the TiVo, I've got wishlist searches (keywords, types of programs, whatever), season passes (record by program, whole season, with timing presets, etc.), and scheduling by program name. That's half the advantage of a DVR, to my mind.

I am the Doctor, and THIS... is my SPOON!
