What is macrovision?
Macrovision is a form of copy protection encoded into DVD discs that prevents people from making illegal copies. A standard DVD player contains a special Macrovision-enabled digital-analog conver chip that is activated when a DVD is played. The activated chip applies copy protection to the analog output and causes copies made on most VCRs to be substantially degraded.
