I have a series 2 (TCD24008A ) with lifetime service that I've upgraded the harddrive in the past. It works great (analog, I know, but I'm happy enough.) Charter switched my area to completely digital and forced us to get a cable box for every tv in the house.. Thanks alot Charter The cable box seems to work well enough when I plug the AV cables into the TV.. red white and yellow.. but when I plug them into the tivo and do the guided set-up, when it asks if I can see a picture in the background it is just black behind the words. I can then remove the av cables from the tivo and put them into the same input that the tivo goes into the tv at and the cable shows up fine. I've also tried both with coax and the same thing happens. Any suggestions on what I'm doing wrong, or is this the end of me recording cable tv with my Tivo? The set-top box they gave me is a Motorola model DCH3200.
