I've been trying to get my receiver to recognize my PS2 for games and dvd's and such. I have an optical cable, and have hooked it up to my receiver, but it seems that I can not get 5.1 to work on DVD's, so I imagine its not working properly on games either. I have the optical out thing turned on in the system config stuff. My receiver is a Sony with 450 watt and is DTS ready. I think the main part of the model number is 740, but I'm not sure and its not on the front of the receiver.... Any ideas? I tried searching the forums, but the search function kept spitting out my searchs... Thanks!
