I was psyched to get my HD service (cablecard) from Comcast, but I dont get any channels appearing on the TV, not even the non hi-def channels. I'm guessing the cablecard blocks any signals coming out of the tivo? I heard that tivo is going to come out with a high def box next year, so I guess I'm out of luck watching HD channels through tivo till then. I have the Panasonic PT-44LCX65 with built in HD tuner.
