CloneDVD is an useful software to backup your existing
DVD collection to DVD-R/RW or DVD+R/RW. You can not only
copy your DVD collection to blank DVD discs, but also
copy DVDs to hard disk folders. You can also output ISO
image files of your DVDs.

Clone DVD can make DVD to DVD copying come true. With a
DVD burner, you will get true DVD copies of your DVD
collection. It is completely the same as the DVD movie
you bought.
