But i have to have my tivo box channels set to BOX to get a good picture but i get bad sound. When i have my tivo box set the channels to CBL i get bad picture but good sound how can i get both good picturre and sound going only through my tivo box? When i am on the box channel i have to crank up the volume.
Check your cable box's own volume control. It's probably turned way down. If you don't know how to adjust that, call your cable company.
