1. Each DVD player has a cutom key for decoding.
2. Each DVD is burned with a key which will allow it to be viewed on a particular DVD player.
3. Add watermarking to identify the specific key/DVD player (this is the only gotcha, if the stolen copy of the movie can't be tracked back to the particular DVD player using the watermark).
4. When an illegal copy of the movie is discovered, use the watermarking to determine which DVD player/key was used an no longer encode future DVDs with that key.
5. profit!
