No doubt Samsung can have a different policy around the world for firmware to allow or disallow the hacks but there is some evidence that people in Europe are managing to get Samsung players region-free. In Australia despite the suggestions we enjoy a free unlocking service for our DVD players it is not strictly true for Joe Public - the hacks here worked for me without contacting Samsung and I have always applied all firmware updates before applying the hack. The timing on the Samsung hack is everything and the Repeat button seems to be a distinct advantage. It can definitely be done with the disks themselves on a computer with BD burner and software wizardry to produce a region-free disc and as is pointed out in many threads the vast majority of BDs are region free anyway. I and OP are aware Blu-Ray regions are fairly unbreakable although again there are some posts suggesting it can be done under certian circumastances.

I am not convinced it does not work in Europe as there are some reports it has done so. It is also reported as working on Home Theatre models as well as a number of C and D series model BD players. I was quite clear I am in Austraia and have unlocked the DVD regions on three Samsung models - 2 3D and 1 2D, using the same hack as is posted all over the place here.
