Hello, I have a Marantz sr5400. Will be connecting a dvd, digibox, vcr and the TV to it. Is it best to only connect the audio outputs (from the above) to the 5400 and still use my SCART leads for the visual side of things? I'll be connecting the DVD and digibox to the 5400 with component leads. Just not sure on the how/ why of the SCART side of things (or s-video even). The manual is clear as mud.... Any advice?
