DVD movie problem

[dice117]

Hey,

I get this error when I watch all DVD rated movies:

Change Parental Control temporarily to level 8?

I used to watch rated PG-13 movies fine, until today, it suddenly popped up. When I choose yes, it says insert a 4 digit password, which always ends up to be incorrect, since I don't know it.

When I choose no, it says I do not have access to this feature, or something denying me of watching the movie.

What is this problem? How do I get around it, and why did it pop up out of nowhere? I'm the only person who uses the PS2 so I know nobody didn't set a password on it. Thanks for any help.

choose yes and enter 0000 as password.
