I use ripit4me, which uses DVDDecrypter and other programs. I also use DVDFabDecrypter, as well as DVDShrink, VOBBlanker, PGCedit, and FixVTS. One program will not work with all movies. I try and keep the setup files of everything I install so I will have them if the software is no longer distributed, or if a new version does not work (this actually happened with VOBBlanker).
