Yes, macrovision is part of the video signal itself. It is actually an extra signal added to the gain frame or gain section I think. VCR's have a small part called an automatic gain control. It isn't designed to handle signals like macrovision, so when you hook up the video to a VCR the AGC goes crazy, bright, dark, bright, dark, or simply no picture at all.Chippie said:Yup, Macrovision is in the data stream whether its DVD or Video tape
