If you have bought or rented a movie on a DVD sometime in the last few years, you would have had to sit through the compulsory anti-piracy video at the beginning. You know, the one with the urgent death-metal-thrash techno music in the background, and the words on the screen telling you that you wouldn't steal a car, or a handbag, or a television, or a movie. It then goes on to tell you that: "downloading pirated movies is stealing" and furthermore that "stealing is against the law" and finishes off with the bleak message that "piracy is a crime".
