I am relatively new to the increasingly addictive world of home theater, and have just upgraded to digital cable. I have a few set up questions. My receiver is a Yamaha RX-V620, and the only coax audio in that i can find is marked "CD". Can I use that to connect my cable audio? Also, I am running my cable through an ancient VCR that is not stereo enabled and without S-Video. Can I run S-Video directly from my cable box to my reciever, then to my TV? Do I have to upgrade my VCR? If so, what imput would I use? I apologize if I am not giving enough info or asking the right questions, but I just want the best quality sound and video that digital cable can offer.
