Full Moon wo Sagashite DVD problem

[greenground]

I'm ntsc, for my ps2 it is S-video and my dvd player upstairs is RGB, I think it is just the way the disk is coded cause it works on some other dvd players and some it doesnt, like the video store down my street it work on and it works on my friends xbox, but it doesnt work on his dvd so it is just the way it is coded.
