Did / do you also get a different Tivo unit when you changed cards? The Tuning Adapter, Card, and Tivo all need to be in sync in their system so they talk to each other. If the card or tuning adapter is paired to two different Tivos there will be issues. I still don't get the Tennis Channel and the NFL Redzone says no signal. I would think I would get a Red Zone banner on the channel. I will see for sure on Sunday. The only reason I have charter's highest price package with all the movie channels (which I don't need) is to get the NFL red zone during the NFL season.
