I got Sucker Punch today and inside, the discs go like this:

Disc 1: PG-13 Theatrical Version Blu-ray
Disc 2: R-rated Extended Cut Blu-ray
Disc 3: PG-13 Theatrical Version DVD/Digital Copy Combo Disc

Disc 3 is obvious but how to do the others? The only comparison was Terminator Salvation. Would I make the main (parent) profile the Extended Cut (since the main artwork states as such) and then make the Theatrical Version disc as the child profile?

The disc themselves are not labeled as Disc 1, 2 or 3 (what I listed above is the order it was inside the case).

I know this will result in a long debate about profiling these like Box Sets (which I'm leaning towards now), but until the rules change, what to do in this case?

I always profile based on the front cover so, if the extended cut is what is listed, then that would be the main profile for me.

As an aside, how did you get this a week early? 

Quote:
For DVDs with more than one rating shown (e.g. a DVD which includes an R and Unrated version), use the highest applicable rating with the following scale:

    NR < Board Rating < Unrated < Adult.

That's the only thing that I found in the rules regarding a situation close to this.

Since this is all one film I would use the highest rating that the film received.

In this case, the Sucker Punch Extended Cut is rated R and is 18-minutes longer than the theatrical version.

I Am Legend is another example. I go with disc 1 is the main feature and anything after that is a bonus.

I would also do the Extended Cut as main profile

Not releated to the OP but I just roll my eyes at the studios when they do this. Why not use the features of the format and use seamless branching?

But since this is one film, I would still treat it as if it was two versions on the same disc. Not a box set, not a bonus profile, just profile the longest cut.

Well, in this case, I know the studio had Snyder cut out the musical sequences and this "Extended Cut" was submitted to the MPAA and got an R rating.

As for why seamless branching wasn't used, Warner has Maximum Movie Mode which in itself is like seamless branching but with MMM, it stops the movie for video commentary with the filmmaker or with PIP of storyboards, etc. So with that, I don't think seamless branching was a possibility (especially since MMM is for the Extended Cut).

And that was the same reason why seamless branching might not have been used for Terminator Salvation.
