I'm trying to figure out this whole home theater thing. I have a Panasonic SA-HE100K Home Theater Receiver--my DVD player offers S-Video and RCA outputs. I'm using the RCAs (left/right channel and video outputs) going into the receiver. I have almost no options as anything I do I get a message on the receiver that says "not available in 6 ch" over and over. I'm wondering if I use an S-Video cable if this would have any impact about getting the surround working. Or if I need some sort of different RCA cable, or even a new DVD player. Just not sure what direction to go in. Thanks!
