I was wondering if there exists a way to uniquely identify one DVD from another if they are the same movie. For instance, how can I tell the difference between my copy of “How Stella Got Her Groove Back” and my friends copy?
I was reading up on the Burst Cutting Area that was used for DivX back in the day, and it seems like a possible solution. Is this area even used by DVD production facilities these days? If so, would two of the same movie have a different serial number encoded in the BCA?
Does HD-DVD or Blu-ray have something similar to BCA?
