I've sampled quite a few various programs that will backup any movies you've got, whether it be copying the disc to another disc, or to the hard drive as a DivX file, or whatever other format it chooses. They seem to take a very long time, much too long to bother putting up with on a regular basis. DVDFab will zip through a movie and copy it to a DAT file a lot faster than anything else I've tried. Whats more, it gives you the option to copy to blank DVD and will even split the movie among two disc if it happens to be on a Super DVD that holds twice as much info and so can't be simply copied to a regular DVD-R. It also makes everything look so simple, you wonder why others haven't managed to master the same thing...
What I'm saying is....DVDFab kicks ass PERIOD
Best:
Fast
Real easy
Worst:
The color scheme is quite ugly
