Having added a Z2 to our home cinema setup, our trusty old Sony 725 is starting to look like the weak link. We've just installled 14m of Belden 1694 component cable for the Z2 (Mark Grant special), so DVI etc would only be of interest for future proofing. I'm still a novice regarding the whole progressive scan lark, but I gather that I need to be looking for at least 575p output (is 720p possible over component?), and the player should have a better de-interlacer than the one onboard the Z2 to make it worthwhile. Any recommendations?
