If anyone who owns a PlayStation 2 wants to modify it to output RGB (SCART) without a green look with DVDs then you should read this page:

You will need to open the console and provided it is a UK model SCHP 30003 it WILL work. I did it last year, and have had no problems at all. It`s so much better as I don`t have to switch leads to watch DVDs or play games.
There are pictures included of my PS2 and full instructions.
This does invaliadate your waranty.
