I have a Dish 520 but only using one TV right now. I have the condo pre-cabled but the Dish install guy told me that I can't use that to connect my tv2 because exsiting cabling is not connected directly but goes to a cable box (Comcast) and they can't touch it. 
I tried anyway and found out that I do get the reception (Dish dvr tv2 out -> outlet in living room -> outlet in bedroom -> tv2) but the quality is really bad. My question is, does anyone know how a typical comcast cable box would look like and if I can fix this without getting Comcast involved?
