Seamless branching providing multiple versions of a movie on one bluray.

Usually look at the number of chapters, the length (time) and the languages available.

Unless they've used seamless branching to provide alternate versions (theatrical and director's cut, for instance) it's usually pretty easy to spot the one you want.
