Guys. I have the HTR540 Onkyo AV Receiver. It has analog out's for audio, but I have no experience with this. I have always used optical or coaxial for my sound. Exactly how does this work. Are there options to set in the menu. I would assume you use RCA cables of some sort to connect the HDDVD/Bluray to the AV receiver. Do you all know of some type of guide or can you posssibly explain how this works.
