i have the denon 3801. i've had it for 3 years now. it has worked great. i have 5.1 setup in the main room and two sets or speakers upstairs and outside on the 7th channel. i have sattelite tv using the microsoft ultimate tv receiver. when i switched over to it from the regular rca, the sound was no longer carried over the 7th channel to the multi-room speakers. i found it strange but couldnt get it fixed and lived with it. i just got a new dvd player and now, it does the same thing! how in the world could a signal not be carried over the multi-room speakers if its playing fine in the main room? the cd-tuner-xbox all work fine. any ideas?
