First you need a program that will rip and de-ccs the dvd.... so use a program called dvddecrypter to rip the dvd to the hard drive. Then you need to make it fit on one blank dvd disk, so use a program like shrinkdvd or dvd2one. after that you can just burn the compressed data, which was made by using dvd2one/shrinkdvd , by using nero 6 or something similar.
