if you have a copy of windows laying around install windows via boot camp... ripit4me, dvddecrypter, dvdshrink, img burn (all free)
mactheripper has gone crazy recently and requires a "donation" to use the latest beta releases... 2.6.6 is outdated and fails on many current dvds, however you can still find mtr 3 r14f floating around, which will work on a lot of films... the current beta i believe is r14i however there is no way to get this working without spending money... even after using mtr if you want to shrink the film to fit on a single layer dvd its going to cost even more money for a program like DTOX (dvd2one) since there is no free mac dvd compression software.
