The Motion Picture Association of America is currently fighting to ban DVD copying, fearing widespread piracy as DVD burners become more commonplace, but 321 Studios keeps its package aimed at legitimate use. The software copies video object
(VOB) files, but provides no access to these files, which carry the
MPEG-2 stream as well as navigation and search information packets.
So you can't, for instance, step in to remove region protection, which would enable playback on any drives sold anywhere in the world.
Also, 321 Studios inserts a DVD Backup warning screen on the final discs to remind those watching a copy that it was never intended for resale or distribution
