Firstly u will need to rip the dvd to hard drive. I like to use DVDFab or dvd decrypter. copy the main movie to hard drive and then download a program called "StaxRip". This is a very good front end gui, its very user friendly helps to automate the process. Follow the tutorial on you-tube on how to use StaxRip.
