Is there any way to copy a DVD's contents to your computer. We were trying to copy some business videos to a folder on our computer so that they would be more easily accessible.
Two methods:
1) MacTheRipper is a fine app for doing exactly this: Put a DVD in. Create a new folder on your desktop and name it, perhaps, "DVD importing." Then open MacTheRipper, and go to File > Save To… to choose that folder. It will save the DVD information inside two folders called AUDIO_TS and VIDEO_TS. You can use the wonderful, free media player VLC to open that VIDEO_TS folder.
2) AND THIS IS PROBABLY THE WAY YOU WANT TO GO … You can use HandBrake to import the DVD content (or an imported VIDEO_TS folder) straight to a QuickTime- or iPod-playable movie.
Of course, we would never ever want to use these techniques to distribute copyrighted content, would we?

Yeah! An update! :-PG-man
VLC is a truly great piece of software, but your trusty Apple DVD player will also open/play Video TS folders.
