i have a mid 2010 macbook pro laptop can i play a region 2 NTSC format dvd on it without problems?

It would have been useful to know what region you are in!

DVD Player: About DVD-Video Regions

Region encoding is the mechanism that enables motion picture studios to control the worldwide release of their movies. It is required by the DVD Forum (http://www.dvdforum.org/forum.shtml) in all commercial hardware DVD players. Every DVD-Video disc contains one byte of data representing a region code, which limits where the disc can be played.

Once you have set he region in DVD Player five times it cannot be changed.

Instead, use VLC to view videos from different regions:

Then that shouldn't be a problem, but I am puzzled as to why any NTSC disk is region 2 where only PAL is used.

And I don't understand your reference to 'formatted'. DVDs are not formatted, they are a recording media that can accept anything digital.

What kind of DVD is this?

I am equally surprised that they would release a version for region 2.

Use VLC for playback, not the Macs's DVD Player and you should be fine.
