ntsc pal
All Pal European Dvd players can play both NTSC and PAL discs. But this is separate to Region encoding. Even if you have a non multi region dvd player it will be able to read the dvd but tell you it's the wrong region. So ignore the Pal/NTSC issue and just check that the player is region free.
(I believe that most NTSC players however, cannot play PAL discs).
