I recently purchased the Series II Humax/Tivo 40 hr DVD burner to use with my digital cable package. Since I've hooked it up the picture looks considerably darker and slightly blurred and the colors arent as brilliant as they were pre-tivo. Additionally, I cant view my HD channels any more. Is there a setting I missed? A trick or two perhaps that will help me? This is my setup by the way.....From the wall outlet, to the digtial reciever, to the Tivo box, and then out to my TV.
