Just setup my new system. I have a coaxial cable running from my DVD player to my Amp, and a scart cable running to the TV. Everything seems to work fine and I get great sound from watching DVD's. However in the manual of my amp it says I should connect my DVD player to my amp using a video to video cable and a phono cable for left and right sound. Am I right in thinking that the coaxial cable does both video and audio and is the only connection I need between my amp and DVD player.
