all of a sudden I am not getting anything out of my reaer speakers. I watched the pod race scene tonight in 5.1 and put my ear next to each of my reaer speakers and nothing. I checked the test tone with my receiver and they sound fine. My connects are fine. I never had this problem in the past. do you think it could be my piece of crap apex 703A 3 disc changer dvd player? Any suggestions would be great thanks!.
