I am not sure how the best way to connect these. I was thinking of getting a fully wired RGB scart cable to transmit pictures and sound. I read somewhere that scart is only good for pro-logic sound. Can I use a picture only scart and then use separate cables for the sound? The TV is dolby digital 5.1 but I don't know if the sockets at the back of the sky digibox are optical/co-axial - they seem to be just ordinary left and right audio out. What sound quality does sky broadcast in? Any help would be gratefully appreciated!
