Multi-region in the U.S. seems to be a right pain in the backside. Here in the U.K. even our VHS players could output NTSC.
One thing worth noting -although I have no idea if it applies to America- but there is a difference between the terms "Multi Region" and "All Region". The latter defeats the region check, therefore allowing the player to play anything. The former specifically changes the player to the region of the disc inserted.
Adding to what Eric said, I would assume that a multi-region player would naturally convert PAL to NTSC. Certainly I would assume a U.K. player would, but as I already said, Europe seems more friendly to playing other peoples discs!
By the way, what's the film?
