Macrovision and other copy protection schemes can be removed completely and permanently from copies with the use of a Time Base Corrector. It's a $400-$700 piece of video studio gear that strips out ALL the color sync info on the original and replaces it during playback with a generated clean solid signal. Studios use it to stabilize images from several tape machines or cameras so that switching can occur seamlessly.
