Data DVD-ROM protected with Safedisc 4

I have a DVD-ROM that is protected with safedisc 4. It is not a game DVD it is a data DVD. The DVD is also dual layer. Does anyone know how to make a working copy of a data DVD and if so what program and settings. Have tried almost every copying program (i.e. alcohol, clonecd, discjuggler, blindwrite) with no luck. Please help. Thanks in advance.

Unfortunately, it isn’t presently possible to make a working copy of a safedisc protected dual layer dvd.
