Hey guys.  I finally got my home theater setup and I love it.  I'm so happy that such a great site like this is available for beginner audio/vidiophiles such as myself.  I recently purchased the Pioneer VSX 815-S 7.1 Channel Receiver, the JBL SCS300.7 Sat/Sub speaker system, and Pioneer DV-588A-S DVD player (My tv is just a flat screen 27" Sony Wega Trinitron, but does the job for my small room).  I have it all setup in a small 14' x 10' room and it fills it VERY nicely.  Here's my dilema...  I hooked everything up (only in 5.1 for now) and placed all my sats and subwoofer where I think I'll get the best sound.  I have all connections tight and bright and correct polarity.  When I go to advanced setup to use Pioneer's Auto MACC I get near the end of the setup and I get an error that reads something like "Err SBch".  I checked the manual and it says to check the surround back speaker connections.  Everything appears to be fine, yet I get the error everytime and it's becoming very frustrating.  Has anyone else experienced this problem before or have any advice for me? TIA for any of your input
