Hey guys, I'm trying to get the AC-3 out of my system. I've got a Pansat 2500A and a Sony STR-DE475 receiver. I can see where I've got to plug a line into the S/PDIF on the Pansat. There's something called a Digital Optical TV/SAT plug in on the receiver, is that where the other end of this line goes? Is that the only connection needed? If so what kind of cord do I need? Thanks to anyone who takes the time to respond.
