it depends if your dvd is region-locked. but most dvd players today are sold 'unlocked', meaning you can play any disc from any part of the world.
regarding hacks however, there are ways on how you could unlock the region code of a dvd player. especially with samsung, i think there are simple steps that you use on your remote control to make the player region free. i-google mo lang.
OR... bili ka na lang ng region 3 na godfather collection...
