DVDShrink

DVD Shrink is software to backup DVD disks. You can use this software in conjunction with DVD burning software of your choice, to make a backup copy of any DVD video disk.

DVD Shrink will also burn your backup DVD, if you have installed the latest version of Nero. You can download a demo version of Nero here. If you already possess alternative burning software and prefer to stick with it, then you can still use DVD Shrink. The output from DVD Shrink can be saved as files on your hard drive, which you can then burn with software of your choice.
Why Use DVD Shrink :
Most DVD titles are designed to prevent you from making copies.

The first preventative measure is encryption. Most DVD titles are encrypted, which prevents you from either copying them to your hard drive, or if you manage to do so, being able to play the resulting files. DVD Shrink overcomes this problem with built-in decryption algorithms.

The next problem is not so easy. Most DVD video titles are simply too large to fit, without modification, onto a single recordable DVD-R disk. DVD Shrink overcomes this problem by modifying or "shrinking" the data from your original DVD.

DVD Shrink provides two ways of shrinking your DVD disk. These are re-authoring and re-encoding. You can use one, or the other, or for maximum "shrinkage", both combined.

Last but not least, why use DVD Shrink? Because DVD Shrink is free!
