What are some DVD Unprotecting software?
Solution 1:
Try AnyDVD from Slysoft, http://www.slysoft.com/en/ They have a suit of products that allow you to unprotect and copy the DVD on your hard disk.
Solution 2:
DVD43 is a free decrypter. It can be used with Nero, Roxio annd many others, although for ripping DVDs (and other encoding tasks) I like Handbrake.
