I just bought a Denon AVR-28002 A/V receiver and I am very satisfied with it! This is really a high quality unit! I have many components connected to my receiver. Thus, all my analog and digital connections are used on the rear panel. In fact, the only connections I don't use are the EXT-IN and PRE-OUT connections (except for the Subwoofer connection). However, I have a problem: When I plug in my headphones on the front panel, I cannot listen to anything else than the DVD source!!! If I simply switch my source to the tuner or the TV or to anything else I can still listen to the same source from the DVD but nothing else!!! What is going on? Would I need to do a reinitialization of my unit? Please help me out. Thanks for your collaboration.
