If it's a DVD navigation system,chances are that it was created with a BLUERAY burner, I have tried copying mine so that it does not get ruined, I use
ANY DVD as a decrypter and Nero as my main burning software. For movies I use
1Click DVD Copy Pro, this is a brain dead simple program to use. Back to the NAV disk, I was unable to copy it due to the fact they used BLUERAY to create it and when I checked the NAV disk it stated that the program was 12.5 gigs, so even if I was able to do a dual layer burn, there still would not be enough room. BLUERAY is awsome and I will be upgrading my home and office system to it once a stable format is adopted and recognizd as a standard for the next generation of DVD players and burners.
