I am having a major problem with my 4802 and am completely baffled. I am hoping some members are going to offer some good advice. I have had the 4802 that came with the touch screen remote for a couple of years. I run my dish 921 audio with fiber optic through it. Picture is fed independently via an HDMI cable since the 4802 doesn't offer HDMI switching. I select dbs/sat for the audio from my dish 921. I also have a Denon 2910 DVD player that I run audio through a coaxial cable input. The picture is fed via component cable I also connect my computer through a fiber optic input on the VDP input for audio playback only purposes. I just purchased a Sony DVD recorder, and for the life of me I cannot get it to play back any audio, unless I connect to the inputs where my dvd player had been connected. When I do this the Sony will play back in full 6.1 DD or DTS no problem. If I then try to re-connect the 2910 to a different input, then that won't give me any audio. I have tried using a fiber optic cable and coax cable for audio and have re-assigned the digital inputs on the Denon 4802. My question for the members I guess is this, "Is it possible that some of the digital inputs could have gone bad on the 4802. Please bare in mind that I have tried re-assigning fiber and coax in the 4802 set up menu all to no avail. If I switch the cables around that on one of the working dvd players both will perform perfectly, so I know the DVD players each have their own repsective menus set up correctly. Any takers on this one? Sorry to be so long winded but I wanted to explain as much as possible.
