Some companies have developed a pin-head sized chip that will stop thieves from being able to view prerecorded DVDs.
The story is on CNN.com and comes from the Associated Press.
Since this link will eventually become inaccessible, here's a description of the technology (used for educational purposes only):
"A chip smaller than the head of a pin is placed onto a DVD along with a thin coating that blocks a DVD player from reading critical information on the disc. At the register, the chip is activated and sends an electrical pulse through the coating, turning it clear and making the disc playable."
