Sponsored Tournament Question

I'm going to do a sponsored tournament.. and was going to give a DVD movie (hockey related obviously!), but.. how do you get around the Region? I see the Lost Blobby's tournament is giving a copy of a movie, but.. what if someone in the UK wins, or Germany? Do most DVD players play other regions now? If I buy one, it will only be Region 1.

many machines have the option to type a code so it becomes region free. or the winner should use dvdshrink to make a copy in region free(you may if you have the original).

If they don't have a DVD burner?

I think it may be a region free DVD.
