I'm in the States. Stuff here is NTSC.
My Apex DVD player can handle both PAL and NTSC discs, and if (during setup) you've told it your TV is NTSC, it'll play ANY disc back in NTSC format, converting if need be. A PAL disc borrowed from a friend played back fine on the Apex.
I'm pretty sure I've run the disc in my LiteOn as well, and it also was able to handle the PAL disc, producing a normal, viewable picture on my NTSC television.
I'll go double check.
