> It's about price differentiation between different regions. I thought the DVD region locking had to do with the old school movie distribution rights systems that were in place. i.e. Fox would sell the rights to their movies to multiple companies in different regions for redistribution outside of North America. Allowing a person in one region to buy a DVD from anywhere would mean that those regional rights holders would otherwise lose money on their investments.
