There is Mac The Ripper 4.0 which in my experience can rip anything one way or another. There are hoops to get and install it, and some review to figure out the various settings that I'll leave others to figure out for themselves.
I recently got a new iMac, though, and MTR 4.0 is on my old machine. However, on the new machine I find I can use Handbrake 64 bit with VLC 64 bit and rip/convert a movie from my external DVD burner (USB) in about 20 minutes. It took 25 minutes for Toy Story 3. That is quick enough that I may not rip disks beforehand to cue them up for Handbrake. Note that the VLC 64 bit is not the latest version of VLC and you have to hunt around to find it, and you need the VLC 64 bit to go with the Handbrake 64-bit. It is my SOP is to use the title specific mode on Handbrake, and this procedure is necessary on difficult titles. In my experience, title specific mode in Handbrake never fails, even on the latest and toughest like Toy Story 3. In brief summary, to use title specific mode, figure out what title you want (start watching the feature on the computer with DVD player and click on title in the DVD player window) when you first launch handbrake and it asks for source, click cancel, then go to the top under file (?-this is from memory and may not be 100% correct), then select tile specific mode (?), then open, then enter the correct title when it asks.
