OS X DVD Player region code dialog box
by Richard
This dialog box popped up when I tried to watch an IT Crowd DVD from the UK. (By the by, IT Crowd is hilarious and awesome; if you’re even the least bit geek-inclined, you will probably be rewarded should you make the bit of effort required to watch it if you’re not in the UK.)
I didn’t quite expect that I would be allowed to watch the DVD, but I also wasn’t counting on being given the option to change my computer’s region code. Not that this makes me happy — region codes are just another bullshit way that Hollywood tries to control culture in the name of profit.

Just in case you haven’t solved the issue, please never set the region code.
Using VLC for MacOSX (http://www.videolan.org/vlc/) will decrypt the DVD for you.
