Anybody ever have a problem with an echostar/dishnetwork sat receiver not putting out a dolby digital signal? I just got a Denon AVR2505 and notice that it says PCM and doesnt show Dolby Digital, but Dolby Pro Logic IIx instead. On the echostar's menu, I can select Dolby Digital only, but then I get no sound whatsoever, no matter what channel (I thought maybe only the movie channels would use the dolby digital). If I use PCM or the Dolby Digital/PCM option then it works, but only in PCM mode. On the rear of the echostar, it also says "Dolby Digital output" on the optical out, so it should be at least capable. I'm at work right now so I cant call their tech support yet.... any ideas?
