PS2 as a DVD Player

Okay, so every time I put a DVD into my Playstation 2, it asks me if I want to temporarily raise the parental guidance level to such and such because all of the movies I own contain drug usage and graphic nudity and violence and all the things that make American cinema great. I've got a password for it, and I don't really mind having to do it every single time, but... you know, I'd like to just raise it permanently and spare myself some trouble.

I lost my PS2 manual, or else I'd do it myself. So can someone tell me how to get that done?

This is what yahoo answers says Yahoo! Answers - How to break code on dvd parental control on ps2?

DVD setup menu? What?

maybe that screen you get when you don't have a disk in and you start the system up, like where you can change the ps1 rendering modes?

Oooh, I had the same problem some time back. There's a special password you enter into it, which lets you change the password to what you want it to be (for me, I changed it to 0000, then I learned to how turn the controls off).. unfortunately, I don't remember what that special password is...sorry.

When you're watching a DVD, press start on the controller, there'll be several options things you can find to turn off that. My TV's broke now so I can't check!
