Just as you can't copy commercially made video tapes to another VCR due to Macrovision anti-copy encoding, the same applies to making copies to DVD. DVD recorders cannot bypass the anti-copy signal on commercial VHS tapes or DVDs. If a DVD recorder detects the anti-copy encoding on a commercial DVD it will not start the recording and display some sort of message either on screen or on its LED front panel display that it detects the anti-copy code or that it is detecting an unusable signal.
However. I can recommend one firm which can solve it. I have found here such site

They have a device - GREX, I heard that with its help it is possible to block protection DVD and satellite tv-channels and to write down transfers on the dvd. It removes Macrovision.
