DVDShrink is a great free software, but unfortunately its development is stopped (last version 3.2 was published in July 2004). Practically it means that Shrink will deal successfully with older copy-prtection and can shrink the content to the relevant size as well as burn it with the help of Nero (for instance).
So, you need AnyDVD (newest ver. 188.8.131.52) for the newer copy-protection methods.
One of the best "kits" for backup is AnyDVD and CloneDVD2 (www.slysoft.com)
