To begin with, there's a serious encoding problem on the 2nd disc (the international version), around the 1:50:20 mark, where, depending on the resilience of your player's MPEG-2 decoder, either a bunch of colourful blocks appear, or - the better option - a small portion of the screen moves in a different way than its surrounding. The whole thing lasts less than a second, and in the latter case is hardly noticeable at all. AFAIK, CJ Entertainment are aware of the issue, they pulled the faulty first pressing off the shelves, and corrected sets should be available shortly (might already be)...

OK, now that I mentioned the international cut, approx. 5:23 shorter than the domestic one, let's have a look at what the differences are. Following is a visual index of the missing footage (the screenshots come from the Korean version; mouse over the images to see the number of frames missing @ the given time in the international version):

BUT, although being shorter, the international version still contains 1:15 worth of footage not included in the longer cut (here's a sample from the scene in question).

Last, but not least, there are a couple of scenes using different/altered shots:
