The install didn't go well. The installer brought an M card, I put it in, the TiVo recognized it and everything was looking up. Then, testing the channels, only a very few showed up. Mostly the local digital stations, and one or two of the normal digital tier stations, and none of the old analog channels. The guy had the dispatcher call Comcast but was put on hold. He had to leave (another appt....and I was pissed), so I have a non-functioning CC install. I complained and their tier two person said that it was most likely a bad card. She did verify the serial number of the card, as well as my account information. We have setup another appointment to have a tech come out, but I am going over to the local office and demand another card, which I will call in and activate (read a few numbers). Why Comcast thinks plugging in a card and reading off a few numbers is worth $20 is beyond me. Does anyone have a good list of Baltimore Comcast unencrypted channels since I think those are the only ones I'm getting? If thats the case, the card seems to be working, so does anyone think its still the card?
