Hi there, I can play CDs on my DVD player thru my home theater receiver but when I disconnected the HT spea're kers from the front speaker connections & connected regular Polk Audio speakers (in another room) I can only get one speaker at time to work. I've tested out the wires & speakers & they're OK - can anybody tell me what I'm doing wrong? The CD plays in 5.1 mode, if that makes any difference. I would appreciate any help!
