Hi... I'm a newbie on this fine forum and I've read and searched posts until my eyes started crossing, so I'll just ask: When I push either the "Setup" or "Menu Guide" buttons on my Denon RC-921 Remote Control, I see no menus on the Denon A/V receiver window. If I push the "Channel Select/Enter" button, I see a few speaker and fader options but that's all I seem to get. What am I doing wrong? Thanks!!!
