Hi, Does anybody know if there is a difference in picture quality between using S-VIDEO and RGB, via a 21 pin SCART cable? I have the option of using both for DVD play back. Also, does buying expensive SCART leads make much of a difference over cheap leads. I imagine it would on a mega expensive setup but on an average person's setup I can't see that its worth forking out £30 or so just on a lead??? I have a 28" panasonic widescreen tv. Thanks for any help.
