I live in Boston area and have Comcast as my cable provider. I have an older TIVO Series 3 (not HD) dual turner box and was using the cable from the wall to connect to the box. I had no need for the cable box as I watch the basic channels. Comcast is upgrading to digital and I started to get a white box pop up while watching TV that my TV has no equipment needed for the future Comcast enhancement. I called them and they said I need digital converter. Picked it up and after the activiation I could not get any channels. Called their tech support to find out that digital converter is not compatible with Tivo and I need cable box but to call the sales dept. Called them to find out that I need cable card and they will charge me 6.45 but need tech to install it. I have been getting so many different answers that I don't know which one is correct. Is the cable card going to work with my Tivo? Do I need two cable cards since I have dual turner?
