OK - I give up. I have read the manual (wow that was really useful...) and tried all the combinations of settings that I can think of, but I still cannot output digital audio via Denon Link. The options in the DVD set-up menu are greyed out. Why? BTW have connected the Denon link socket to my 3805 AV/Receiver's corresponding socket, before anyone suggests that. I have set the digital input to Denon Link, so that half of the equation is sorted. I think.... Help!
