I have a Series 1 Tivo that I use as a recorder. I just moved it to another TV where I don't have a cable box - previous one had a box. I want to change my input source so I assume I need to go through guided setup. Since I don't have a subscription I can't dial in. How can I reset my input and not dial in and finish with Guided Setup? I am now stuck - can't dial in and can't finish guided setup.
