Any north american PC with a DVD player can play PAL as well as NTSF. (Good thing to include when selling PAL DVD singles online).
NTSF....National Television System ...Frogmorton? Fahrquar?.......forgotten?...

We could always just pretend it was a typo -- the letters are next to each other.
NTSC: "Next Time, Spell Check."
