Are there any other differences? I don't think, I may be wrong on this, that TIVO services work with Cable TV other then the normal DVR activities.

I think you have about nailed it. TIVO is a DVR with extra functions. Better ways to program it to record the shows you like. It will even learn what you like and suggest other shows that you might not have known about. It's in touch with the TV guide instead of just starting and stopping at dates and times that you have given it.
