I have tried dvd decrypter by making an ISO image and then using dvd decrypter to burn the image back. When i placed it in the navigation system, it would error out. I did notice in dvd decrypter, it said that it took out a macrovision protection.
Do i need to place this protection back when i burn the image back?
I also used nero and made and image and burned it, didnt work either. It would error out in the navigation system.
Also, what are some programs which check for protections on the dvd?
