Anybody know what checkpoint packaging is on dvds?

what is the difference between a regular dvd packaging and checkpoint packaging?

Checkpoint makes the anti-theft things that are at the doors of retail stores. The ones that say "we're sorry, but the Wal-Mart inventory control system has been activated" when it gets set off. So I would assume that the Checkpoint DVD packaging has the magnet inside that sets it off.
