After a DVD is created, the original source material can get lost or damaged  When this happens, there is no easy way to get the video off the DVD and back into the computer where it can be re-edited.  DVDxDV makes it easy to get at your video when it's on DVD.  With DVDxDV you can quickly convert the DVD video back into any Quicktime video format.  From there, it can be re-edited and burned onto a new DVD.
