And how to define the main cut? This is easy if the producer clearly states which cut is the main feature and the others were only a bonus. But when all cuts are equal in the package, every user uses different criteria to weight the importance of the cuts.

If there is no obvious attribute which selects the main profile, the film version which is listed first should be  used for the main profile.
