griffin,

some Blu-Ray movies are region free and some aren't. Amazon.com normally says if it is or not, thought they have been known to be wrong on occasion and people have been left with movies they cannot view.

The place I go to in order to get accurite Blu-Ray movie region info is this website:
http://bluray.liesinc.net/

- hasn't lead me asstray yet

and on it you will see that the Transformers 2 Disc Blu-Ray release is Region Free

Pulse,

unfortunitely I don't believe it is that simple with the Blu-Ray players, well at least not with a PS3
