Hi, I just got a new 42" panasonic plasma tivo with an HD Tivo. I am currently using the Tivo HD for stretching of standard broadcasts but it does not do a very good job. THe local channels are coming wthrough DTV. Since the Panasonic I hear has greater stretching abilities (better quality) than the HD Tivo, can someone tell me if its possible to use the TV's stretching abilities rather than the Tivo's? Thanks!
