Think that a DVD enters your device and gives you the following message: "This DVD will be deleted in three days." The company Spectradisc has invented a system to stop working the DVDs within a certain period of time. When the laser comes into contact with the surface of the DVD, a chemical reaction will occur and the disc cannot be read within a given time. This would be the product of renting commercial videos and demo.
