I have an older Tivo - I think it's a Phillips Series 2 - with lifetime service. I added an ethernet adapter a few years ago. I checked my Tivo this morning and I'd lost all my channels above 60 - when I checked the cable lineups, I only had two options, basic and extended basic. (Extended basic is selected but it doesn't offer all the channels that I normally have with extended basic - I have Comcast.) Usually I have about a half dozen choices of cable lineups. If I tune into the channels manually, they're still available through my cable box - Tivo just isn't recognizing that they exist. I didn't get any message from Tivo about removing channels. I'm trying to call in again and if that doesn't work, I'll try a reset, but any ideas? It's very frustrating since most of my scheduled recordings aren't working because the channel no longer exists, according to Tivo. Since my Tivo is so old (I bought it in about 2000), I assume I no longer get any service from Tivo in terms of calling them and asking for help.
