|It seems that Sony didn't do it's home work as it still is possible to playback Region 1 DVD's (US) on a PS2 even with the latest drivers installed, which should have prevented this in the first place!
Here are the instructions how to do it:
- Load the DVD into the PlayStation 2
- At the browser screen, select the CD icon then press and hold square and then circle until the DVD menu appears, holding both buttons all the time.
- Then there are two ways to play the movie; you can either select the play icon or the movie start icon which is in the middle to the far left. If one doesn't work the other one will.
