Hi All, I am really stumped. Noticed my rear LH speaker was not working at all when I played anything (I have the TV, DVD and iPod hooked up to the surround sound). Played with the amp settings but no luck. Not a settings problem. Swapped speakers around to test if that was the problem but still problem was with rear LH. OK, not a broken speaker then. Put a surround sound test disc in. Rear LH test sound coming through front speakers (sounds distorted). Swapped a few speakers around in case one of them was "tripping" something. No change. Had a spare amp so I swapped that around. Now things get odd. Sound from TV and iPod now comes through crystal clear through all speakers but still no rear sound (LH or RH) from DVD player. Swapped DVD players - same problem. Swapped all cords going to and from DVD player. Same problem. Now I'm lost. It's not the speakers - they all work fine when playing anything other than DVDs. It's not the DVD cables - I swapped them. It's not the DVD player - I swapped that. It's not the amp - I swapped that. Any ideas?
