What is Macrovision DVD copy protection?
Macrovision is a company which creates copy protection schemes and Macrovision also refers to the copy protection process used on DVD-Video. Macrovision is activated during the DVD authoring stage (when the disc content is created) by setting certain Macrovision copy control bits to the on position. When a replicated disc, with these bits set, is played back in a home DVD player/recorder, the digital-to-analog converter chip within the DVD player applies the Macrovision copy protection to the outgoing signal, causing any copies made on 95% of VCRs in the marketplace to be substantially distorted. There are three levels of Macrovision copy protection.
