Dvd Shrink
Great program for Shinking video files to fit onto a single layer dvd.
DVDFab HD Decrypter 4.0.5.5 (Jan 23, 2008)
This is my personal favorite for decrypting a store bought dvd for backup.
With this program you can choose to blank out subtitles, menus, commentary and different languages.
Updated verions are available at www.dvdidle.com/free
Dvd Decrypter
Great program for doing old dvds with very little protection (also used with rip it for me.)
Vob Blanker
This very basic program is used to get rid of errors in vob files (dvd files created from Fab Decrypter.)
Allowing them to be run through Dvd Shrink.
