To the best of my knowledge:
1.AnyDVD and CloneDVD are sold seperately by the same company.
2.AnyDVD can crack the movie copy protection and also can
rip the movie to your hard drive.Then you can choose
another program to backup your movie.
3.CloneDVD can't rip a copy-protected movie to your hard drive.
You'll need another program to do the cracking job.
4.In a word, Slysoft suggests let AnyDVD do the cracking job
and rip the movie to your hard drive by using CloneDVD.
