MTR

MTR (was MacTheRipper)--the Mac's oldest and smartest DVD-backup app.

• MTR -- the complete toolbox, not a one-trick, point-and-click extractor. MTR is intended for making fair-use, backup copies of discs which you've purchased legally.
• Four Extraction Modes: the ISO image, Rip&Rebuild (RnR) for VTS-level editing, Main Feature, and the specialized Batch Title Extraction. In addition, there are five error-correction modes. Edit bad cells before the rip--not afterwards--with RnR. (There's always another way to peel this grape!)
• For challenging discs, a stand-alone application DVDProbe, for deeper analysis before (not during) extraction. Available in all Extraction modes.
• Multiple, simultaneous extractions with chained DVD drives. Each extraction with its own Mode, settings, and save location. (This feature requires at least 2GB of the machine memory.)
• A top-to-bottom rewrite of the entire application code for maximum efficiency.
• User Guide Videos posted on YouTube
• Active v5 Users' Forum for peer tech support.
