DVDShrink is software to backup DVD discs. You can use this software in conjunction with DVD burning software of your choice, to make a backup copy of any DVD video disc.
DVDShrink will also burn your backup DVD, if you have installed the latest version of Nero. You can also 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 DVDShrink can be saved as files on your hard drive, which you can then burn with software of your choice.
