My question is about the video input-outputs on the Marantz SR7400. I have a cable box s-video output going into the dss/vcr2 s-video input and the s-video monitor output into the television as recommended. When I test the s-video outputs, (vcr1, dss/vcr2) by unplugging the s-video monitor output and plugging it into the vcr1 output I see the broadcast. When I plug into the dss/vcr2 output I see no broadcast. Conversely if I switch the setup so the cable box s-video output goes into the vcr1 s-video input and unplug the s-video monitor to test the vcr1 output I see no broadcast. If I plug into the dss/vcr2 output I see the broadcast! It is normal that when you use the s-video input on either of the dss/vcr2 or vcr1 the respective outputs do not work?
