You can chose the zone you want, and then play the DVD. It's really cool isn't it ? But you can do this only 5 times. After that, the DVD player wont let you change anymore. BUT I did not quit the DVDPlayer, and I noticed that the zone of the DVD-ROM drive didn't had changed So the big stupid bug seems to be the fact that the changes are written when you quit the DVDPlayer. So what you can do to avoid the saving of the DVD zone change is to kill the app instead of quitting it normal.
