I've been building up my home theater for a few months now. A couple months ago, I got a Toshiba SD-3805 and a JVC RX-7520VBK. Last night, I got a Onkyo SKS-HT500 speaker set. Today, when I went to hook it all up with my dad, we noticed that the connections on the player weren't exactly compatible with the connections on the receiver. I was under the impression that any DVD player (even cheap ones) could do 5.1 sound if it was hooked up to a good enough receiver. Am I totally wrong about that? If I am then I guess I got messed up when buying my player which is wierd since I told the salesman that the main reason that I'm getting all this is for the 5.1 sound and he seemed to understand.
