I just got my replacement 1050 and got everything hooked up. The receiver is all I hoped it would be. I originally hooked up 5 speakers (2 main, 2 surround and 1 sub). Everthing worked as it should. Today I decided to hook up a rear center surround for 6.1. I mainly wanted to hear how much difference it would make. Unfortunately, it is not playing. The display on receiver doesn't show the rear surround as being there. The center surround is turned on.

I hooked my TIVO to opt 1, my CD to opt 2, and the DVD to opt 3. Do I need to also hook up the analog connections to get 6.1 to work? If so, should I leave the optical connections in place or just do away with them? The center surrond does show up if I push the 6 direct on the remote, but there is no sound at all.

Boomer Sooner!
