I'm having problems with my brand new Sony receiver (STR-DE995). I have 2 front, 2 rear, 1 center & a subwoofer connected to the receiver. After using the set-up menu and the "test tone" button on the remote, all speakers respond accordingly. But during ALL DVD playback everything is forced into the front speakers. I have tried all audio settings on the discs. The DVD player is connected like this: OUT Front (l/r) to FRONT (l/r) MULTI CH IN 2. OUT SURRUND (l/r) to SURROUND (l/r) MULTI CH IN 2. Center & Sub OUT to Center & Sub in on MULTI CH 2. I have followed the set-up procedure in the manual and the tests perform correctly, why does it not play DVD's properly? Any thoughts ?
