NTSC and PAL are just two different display outputs. It doesn't necessarily mean your machine is multi-region, but it doens't mean it isn't either.
A lot of DVD players are multi-region these days, and a lot of those that aren't can be made multi-region very easily. Sometimes it requires a little hardware work (opening it up and doing some light modding, or maybe flicking a switch or something) and sometimes it is as easy as getting a "secret" key-sequence off the internet to access a hidden menu or type in a special code.
Do some research on the internet for your own particular model of DVD player. Just go to google and type in the exact model of your DVD player and the words "region hack", for example
