I have an original Tivo and a Premiere. I've never had a problem with either of them. However, for the next few months I'm house sitting for some friends. They get their cable/internet through a small local company. That company does not have M-Cards and I'm not worried about that because my friends don't have a cable box/digital tiers anyway. However, when I connect the Tivo, like I usually would, it doesn't work. When the Tivo is not connected, you have to turn on the tv, then hit select on the cable remote to turn on the cable. When the Tivo is connected, the screens stays black and says it is searching for a cable signal. The cable company tells me that they are not compatible with Tivo. Is this true? Is there anything else I can try?
