how do i use Action Replay Max to play region 1 DVD on my PS2?

[davey1]

I want to view a region 1 DVD on my UK Playstation 2. I've got Action Replay Max, which is supposed to allow multi region DVDs, but it comes up with a message saying "can't recognise your DVD player" and asks me to put in a region x code. How do I find out what code to enter?
Seriously? I can't be the only person who's ever encountered this problem?

This guide is for games, but it should work for DVDs:
