I tried all the Mac tools, including Mac the Ripper. Crap compared to DVD Shrink. I can't remember exactly what the problem was with Mac the Ripper, but it was serious enough that I blew an entire afternoon doing rip tests with it and another similarly PITA tool before I finally gave up and just went full-bore with DVD Shrink.

It may have been its inability to properly isolate the different video and audio tracks correctly, but I can't remember. It does also have a terrible UI.

This is another type of utility that simply exists with poor quality and UI in Mac OS. Rippers and Taggers. transcoding-wise, Handbrake (mentioned by Tom) is pretty good, but I also still have to use FFMpegX (back to the shite UI).
