TRYING TO MAKE A COPY OF A DVD WITH DVDFAB DECRYPTER, IT JUST SCAN AND SCAN THE MOVIE DISC, AND IT IS UNABLE TO READ IT. SOMETHING IS NEW , IT PREVENTS DECRYPTING. DOES ANYBODY KNOW WHAT IS GOING ON? AND IS THERE ANOTHER PROGRAM THAT DECRYPTS, BESIDE THE 'DVDFAB DECRYPTER”? ?? PLEASE REPLY AND LET ME KNOW...PLEASE ADVISE ME.. 
cant tell you. sorry. tiss against the rules so unless a mod tells me otherwise. you’re on your own.
If you try to backup your dvd, DVD Fab is a good one and works in pair with DVD Idle made by the same company. Another choice is 1 Click DVD Copy with AnyDVD or the easy one is CloneDVD2 with AnyDVD. If the software keep scanning your dvd is because you don’t help it with AnyDVD or DVD Idle. All from above are sharewares but is worth it to have them. DVD Decrypter is a freeware but is not the same and also DVD Shrink is free so you can try them.
if your DVD is corrupt as in if theres a read error , no software will decrypt it
