ANYBODY HAS THE SOUTH-KOREAN BLU-RAY?

This is a movie I do really need to upgrade for one simple reason: for some stupid reason my Blu-Ray player can´t display the english subtitles of this movie and this one only (something that didn´t happen when I used to have a DVD player ).
I have the british edition that by the way seems to have the best image ( besides the more expensive south-korean edition ).
I found this Blu-Ray south-korean edition but anybody has this? Is it region A locked? Is it worth the upgrade from DVD or should I stuck with the limited south-korean DVD edition that, while the same price at least can be played in my unlocked ( only for DVD ) Blu-Ray player? Any ideas?
