I saw this on ebay, but there is some kind of master code that you can enter into your dvd player that makes it region free. All you have to do is press a bunch of buttons and works for a majority of the players out there.

I've never bought this thing, but thought was interesting, and for the price, you wouldn't lose too much if it didn't work.
