My DVD will play all region discs no problem (put in a region hack) but there are two types of DVD - PAL (UK, Europe, etc) and NTSC (USA and Canada), just like with VHS tapes. An NTSC vhs tape will not fit into a PAL vhs player and vice versa. With all DVD's being the same size this isn't the problem, the problem is how they are written.
I am not sure if my DVD player supports NTSC playback, so I need to find out by buying a cheap NTSC disc to try out - if it does, then I might buy the box set you have, just for the sake of having it in my collection
