Macrovision video copy protection is existed for Copyright protection dvd but problem with Macrovision is that compatibility is not guaranteed.Some Macrovision signals resemble bad synchronization pulses and some TVs confuse these signals with real synchronization pulses.so improperly designed VCRs, some TVs are also incapable of resolving the Macrovision signal.it is extremely difficult to create a DVD player that can output 480 scan lines per frame in addition to Macrovision control codes.
