Have ordered iscan HD, but a little unsure what cables I may require to get the best quality signal input. Will initially use Component for DVD, and S-Video for Sky+. As regards Sky+, what would I need to get RGB from scart output on Sky box, into the iscan? I understand that the iscan will accept RGB input via the component jacks, but don't understand the implications as regards correct sync connection etc? I understand that this route may be better than straight RGB to component conversion? Any advice greatfully received. Thanks.
