Can someone tell me what the 5.1 analog connections on some DVD players and receivers are used for? Is there any advantage to using this connection instead of digital coaxial or optical? Do they work with other features of the receiver (THX, ProLogic IIx, etc.) to give a 6.1 or 7.1? I noticed only some DVD players have them, but a lot of receivers have them. How will these be used for Blue-Ray or HD DVD? Any answers are appreciated!
