Ouch... I am not trying to be disagreeable, but I believe that trying to use DVDShrink on Hitch Region 1 or Hitch Region 2, 4, 5 (any of these) will be a complete waste of time.
Hitch is a recent Columbia /Tristar release, which means it has Sony's ArCCos copy protection scheme on it. The structure on Region 1 is different than that used on Region 2 and 4 and 5. But, DVDShrink is useless as a ripping tool on ANY of the discs which have the Sony ArCCos.

DVDDecrypter may need help, (perhaps a PSL file, for example) depending on the Region. The other solutions mentioned above by TehGrue are the simplest solution to backing up this one -- AnyDVD 22.214.171.124 or DVDFab Decrypter 126.96.36.199.
DVDShrink is useless in this case, though.
