I can't get my tivo to change channels. It stays on the same channel

I believe that you are already on the right path, your tivo will still be assuming that you are running off the cable box plus you watch dancing with the stars for five minutes one time just to see Warren Sapp attempt to dance and now all of a sudden it wants to record every single piece of televison with dance in the title or discription, but I'm not bitter.

Just re-accomplish the set up and let it know that you are no longer running a cable box. Also tell it that ditching you friday night to hang with it's old high school buddies was so not cool.
