To copy sky + plus to dvd hard drive , backup dvd or vhs tape , clone dvd , time shifted broadcast programs , film or documenteries , vergin media , freeview , this site offers information and advise on software and hardware solutions that require a macrovision remover. Macrovision copy protection has been used since the early 80's first on vhs media and of late dvd and broadcast programs. A flag system (CGMS ) is generated in the vertical blanking period of an analog signal to control the hardware allowing a record instruction for the copy protected media. A common problem is the accuracy of interpritation of these signals which occasionally preventsa time shifted recording.Disrupted or degraded picture quality can prevent legitimate viewing of some video material on monitors, plasma tv and some lcd tv's as the macrovision signal confuses the video automatic gain control circuits (agc).One hardware solution is to connect a device between the signal source and the recording device which uses the vertical blanking period for other purposes. This has been used and to some extent still is for subtitle information to assist the hard of hearing or to insert other information called caption controlsignals . The old Teletext and Ceefax broadcasts used the VBI for this beforeit wasused for Macrovision copy protection. Hardware devices that work on this principle are the VICE1000-2 and the ISPRO scart cable from www.ktvision.com .
