If you don't want the TiVo functions, then just get a Cable DVR. You clearly have no idea what great things TiVo has to offer, so why even bother? Get the Cable DVR and live the blissfully ignorant life.
Or, you can give TiVo a chance and see how beneficial Season Pass, Wishlist, Swivel Search, Amazon Download, TiVoCast, Dual Tuner, TiVoToGo, and all the other TiVo extras can be.
