Cant watch dvd on my ps2!

You should be able to put the DVD in the tray and should automatically recognize it and go into the movie.
What type of media are you trying to watch. PS2's cannot play blu-ray movies.

Causes:

1. DVD has lots of scratches
2. Regional Settings
3. Incorrect DVD settings for PS2
4. No/Incorrect Disc

Remedy:

1. Clean your discs well and avoid incurring scratches. Place it in
its box after use.
2. DVDs have encoding. They are encoded by regions. Thus, you cannot
play region 2 DVDs on a US Playstation mainly because the US
Playstation 2 can only read DVD that are encoded in Region 1 or
those DVDs that are encoded for all regions. Again, US PS2 are
region 1 capable. Japanese PS2s are Region 2 Capable.
3. There are a number of settings for the DVD playback of your
PS2. First is the rating of the DVD. If you want to watch a
rated R movie, make sure your PS2 allows viewing of R movies.
You'll be setting this during the first time that you'll be
watching a DVD. It's just the same as real theaters. It is also
protected with password so you need the person who set it up
the first time in order to bypass the rating settings.
4. Put in a DVD first and make sure that it is a Movie. And,
check #2.

Put the DVD in the PS2 and when the prompt for the password appears, press SELECT to bring up the delete password screen and enter the code 7444. Then register a new password.

just use the master password 5963 you must create a new password.

Ok first try 0 1 2 3 because that is the preset code for the ps2 or if that dont work insert any dvd movie, go to setup and access the parental control settings(press select) When asked for your code enter "7444"; It will prompt you again to type in your password. Type "0000" and then scroll down to the movie rating options and choose "off". Hope it helps you out!

This is the only way to turn "off" parental control lock on the custom setup screen.

1) turn off ps2 with no dvd in drive.
2) turn on ps2 and insert dvd in drive.
3) when it asks about parental password, choose 'yes'.
4) when prompted for password, press 'select'.
5) the prompt will change and say 'delete password'. enter '7444'.
6) enter a new password (0000 works).
7) registration complete, dvd will start playing.
8) once the movie starts, press 'select'.
9) click the 'stop' icon.
10) click the 'stop' icon again (the icon must be gray even when you have it highlighted).
11) navigate to 'custom setup' ('select', setup icon, custom setup icon)
12) move to parental control option, press right directional button, enter password (0000).
13) move down to 'level'.
14) move up to desired level (off is at the top).
15) click 'x'.
16) go back to 'select' menu options, and press 'play'.
17) while movie is playing, eject disk and remove dvd.
18) turn ps2 off using switch on the back, keep off for five seconds.
19) turn on ps2, put dvd back in.
20) happy dance. ;)

put in a disney movie or some rated g flick you should be able to re-set password

Put a DVD into the PS2 and let it try to load. When the screen says chenge to level four select yes. When the entry window pops up,press the select button on the controller. It should say reset password or something like that. Put in 7444. Then when you rename the password put in 0000. You will have to do it again 0000.
Once the movie starts, not the menu screen, but the movie actually playing, Press Select button again. The PS2 DVD menu should appear. Cursor over to the toolbox or Setup, and press X. Cursor over to the third icon, and press X. Arrow down to PArental and press X. Change the Parental lockout to OFF.

I am not completely sure about the procedure here but the numbers are correct.

Put in a DVD, and press select button to go to PS2 DVD menu.  highlight setup menu. Press X.  go to settings I think, and paretal control is there.  Use password 7444.   Usually everyone sets the password to 0000.  Then when you go into the parental settings, turn the level value to OFF

try putting nothing in to the ps2 and then go into the system configuration that should be where the password is :-)
