Hello,
I'm having the same problem as vo1c0m3. I tried 0000 & 9999 and didn't work? When i put a DVD in the PS2 it asks me for my password, i have never entered one and it won't let me go to the option(change password) I'm really stuck here? when I put a movie it won't play, it asks if i want to temporary change the parental level. when i click yes, it asks for a password again ??? There's gotta be a way??
