Hi Guys, Got my Denon DHT-500SD today and just trying to set it up! First question: Manual says positive wire on speaker cable is marked - but could only see feint black writing on silver coloured wire - is that the positive? I've assumed it is. Got everything connected: Denon via RGB scart to AV 1 on TV NTL cable (Pace) box via composite scart to AV2 on TV Video via composite scart to AV3 on TV Am I right in thinking that the sound from cable should be pulled down the scart connected to the TV back to the Denon? If so, this isn't happening. When I switch the function to TV, all I get is the terrestrial tv sound. If i switch the tv to EXT2 - cable - all I get is a hissing sound. Where am I going wrong??? Please help? Is the TV button mentioned in previous threads a different thing to TV function mode - if so, where is it - I can't seem to find it? Sorry to seem like a complete dunce - but I was sure I knew what to do after reading all the threads here.
