I have, on loan, the Denon A11SR. I have connected my S-VHS VCR to the amp using a 4 pin S lead and from the amp to my plasma also using a 4 pin S lead. When I select either the amp's set up menu or OSD from the remote no signal is displayed on the plasma even though the S signal is being received from the VCR. Obviously with this amp it is essential to have OSD and as I am considering purchasing the amp, is it likely to be faulty or am I doing something wrong? The manual is the most difficult I have ever read! Help, please!
