This is one of the reasons that Disney initially disliked the video business.
Disney have been involved in a number of weird IP protection stuff. They developed a cassette that could only be rewound with a special device. It was supposed to be a "watch once per payment" mechanism. They also developed a DVD that would oxidise slowly once it got contact with air. They'd burn a movie, seal it in a special case, and ship it to people. Once you opened the packet you'd get about 2 days to watch the movie.
