make my own SVCD-cable?

[sp4m]

do any of you know how to make a SVCD-cable from a RGB-cable? that should not be to hard... does anyone have the chematics on a SVCD-cable?

I want to get rid of the green-screen on NTSC movies... i think this will be done with a SVCD instead of RGB? (i know the picture will be worse, but it seems to be the easiest way to use a SVCD)

Thnx for all help and a lovley forum!
