All my movie DVDs are green?????

[tHe_BiNk]

Hi,

I have a PS2 (no mods) with a very expensive gray PS1
Sony scart cable ($40) which I used for my PS1 for
years, and now use for my PS2 games, it is a very good
cable for playing games, very nice picture.....
However, when I play movie DVDs they are all green?????
How can I solve this?????
I heard something about a wire on the PCB????
I have a v4 PAL PS2.....

Thanx in advance.....
