I can't even see comparing the two actually. Hm. The Tivo functionality is just always there... you don't think about it. With DVD's i can see having to worry about changing discs. I wasn't aware that there were any kind of Tivo like functionality on DVD recorders. The constant recording of the last 30 minutes feature is kick ass too... which allows the whole pausing/rewinding of live tv feature to work. The Tivo Suggestions and Wishlist features are killer as well.
