Advice please guys I am thinking of getting a iScan Ultra to use with my Panny PW5. I would be connecting Progressive DVD, Sky+ and S-VHS VCR into it. Would I be better off using the S-Video from Sky+into the iScan, or will there be a big improvment going RGB - Component via JS Tech box, and then feeding this into the iScan. I currently watch Sky+ via RGB - VGA JS Tech box, but hate losing the Just Mode on the Plasma. Any ideas?
