You can do this in two ways. You can rip as files and play with software designed for playing dvd-video from the hard drive, like PowerDVD or WinDVD or VLC.
Or you can rip as an ISO image file. Some media players, like VLC, can play them directly. Or you can mount the ISO in a virtual drive and play it in other media players. The mounted ISO will look like a disk in a drive to the media player.
Doing a straight rip with DVDFab HD Decrypter will give you the entire disk or just the main movie, whichever you choose. You can also use AnyDVD as the decrypter, rip the entire movie with its internal ripping section, or use it in conjunction with other programs like DVDDecrypter or DVDShrink.
So, did any of that answer your question?
