You can use Smartripper to rip just the movie (no menu , no extra's etc). This application also makes it region free , removes the css protection and the macrovision protection.
Smartripper can also decode the entire contents of a dvd (just select "all")
If you would rip it via Smartripper , then you could choose
DVDShrink to try and fit all that stuff on to a 4.7Gig output folder. You would not need to "shrink" it again with the copy protection remover.
