Just received the Panasonic SC-HT700 home theater system as a gift. I also have a Dishnetwork satellite system. OK here is the problem...My t.v.,4 years old, only has a coaxial cable setup, which my satellite receiver is currently hooked to. How do I incorporate all three. My system was sent to me with a S-Cable....I think I know the answer to my question. I need to buy a new t.v. Please ....someone give me some advice!!!!
