DVD backup software

I have Toast, Popcorn 3 by Roxio, and Mactheripper but I can't seem to backup my Fiancé's copy of a particular DVD. I am getting the message that the DVD is CSS encrypted. This is my first Mac and I am very familiar with programs for Windows that effectively backup 99.9% of DVD's are there any such programs for OS X? Thanks.

Try this MacTheRipper. I think this only copies. Then use Toast or Popcorn to burn the backup.
