I have been using the free HD Decrypter for some time now. It works great and updates for new movies come out frequently.

As a powerful DVD decrypter, DVDFab HD Decrypter for Mac can copy a sea of DVDs and Blu-rays onto your Mac.
Launch DVDFab Copy product, and load the source
Double click DVDFab 10, and then opt for Copy from the option bar when it runs. Next, insert the DVD/Blu-ray disc you want to backup into the optical drive, or navigate it through the Add buttons on the main UI if it has already in. When the source comes to be an ISO or a folder, you can just simply drag & drop it into the main UI for loading.
Select one copy mode, and customize the output file
Move to the left pane, and click the copy mode switcher to choose the copy mode between Full Disc and Main Movie after source loading. You are empowered to select the output size you need, and you can also define the volume label and select the copying options.
After that, move to the lowest interface, and select the output directory to copy the source to a blank disc, to be an ISO file or a folder, at the Save to part.
Start to copy
Tap the Start button, DVDFab will immediately begin the copying task with leading processing speed while providing the detailed progress info during the process. You can cancel the task anytime you don't want to continue, and you can also set your Mac to automatically shut down, exit program, hibernate or do nothing when the task is done.
