System: Denon 3805, 3910, Panasonic 37" plasma, Tannoy Arena 5.1 speakers and sub-woofer. Home made cabinet (wife hated Panasonic one!) The system, including speakers (very nice!) , works fine. Lots of noise - the opening of Gladiator seemed a good trial! However, I have been unable to get automatic speaker setup to work. I plug the Denon mic into the front panel, mount it on a tripod at the listening position, select the option for auto setup and it says "CONNECT MICROPHONE". I select "Start" and nothing happens - it jumps back in the menu in the same way as "Cancel" does. I thought it was supposed to generate test tones etc? One other question: how does one change Function from the remote? I have to manually twiddle the function dial to select TV and then back to Tuner/DVD. Is this an attempt by Denon to make me take exercise?
