Used Playstation 2 Help,dvd Player?

Okay, a few months back my son's ps 2 broke & we went out to Gamestop and got a used one. It works great, one thing we want to use it as a dvd player as well but it has a parental control on it, and the only way I can change it is if I have the password. & I bought the stinkin' thing used, so I cant just call Gamestop and figure out what it is.The only movies we can watch are rated G. Now my husband owns a Playstation 3, his has a restore option (thingy) that restores the whole Playstation 3. But is that somewhere in the Playstation 2 as well , or are we just Shxt out of luck with this. Please help, (:

Suggestion:

Note, you won't need the password for this so this should work for you!

1. Insert a DVD Movie into the PlayStation®2.
2. You should receive a message informing you that the Parental Level has been set, and asking if youý"d like to allow the disc to play. Highlight "Yes" and then press the X button.
3. A new window will appear asking you to temporarily change the Parental Control to a different level. Again, highlight "Yes", and then press the X button.
4. Another window will appear asking you to enter your Password. Above that window are numbers (0-9).
5. Do not enter your password, but instead, press the select button on your Controller. This will change the text in the window from "Enter Password" to "Delete Password".
6. Using the numbers above the window, input 7444. If successful, you will receive a message stating "Deletion Complete".
7. Press Select. You will now be asked to register a new password. Please select a four-digit code of your choosing.
8. You will be asked to confirm your password selection by inputting the same code once again. If successful, you will receive a message stating "Registration Confirmed".
9. Now you need to turn off the password altogether. The movie should of started playing by now. Press select and chose Setup. Go to the parental control "tab" and set the level to "off".
10. Now you should be able to watch any movie
