Has anyone had trouble with Comcast CableCards in these units? I had a TiVo HD with a Motorola M-Card (issued by Comcast). Everything worked perfectly. When I put the same cable card in the new Premiere, and worked with Comcast to pair the card with the TiVo, I get no Signal Strength, no Signal Lock and I don't get all my channels.
I have called Comcast 3 times now, and each time they tell me they have paired the CableCard to the TiVo unit, and they are "sending signal" ... then they tell me it could be 30-45 mins before the TiVo downloads all the channel information.
Signal Strength, Lock and Program Lock all report "-" (instead of a number, like my other Tivo HD) ...
