Advertisements I have a series 1 tivo that is several years old. Recently I upgraded to HD DVR from the cable co (which sucks compaired to tivo...but that is another story). I want to keep my tivo hooked up in parallel but it no longer has a cable box to control and set channels. If i remember right, the Tivo can be used as a tuner without a box, but i cant find how to configure it to do this. Anyone?
