Hello. Quote:DVD Shrink has encounterd an error, and cant continue. Invalid DVD navigation structure 9mmruger is correct this error usually has to do with copy protection that cannot be handled. Try the programs he listed or rip using DVDFab Decrypter which is free and can handle the new protections and then use Shrink. You can clear out your leftover analysis files from Shrink, this may help. Open My Computer then Documents and Settings, then All Users, Application Data, DVD Shrink. You can delete all but the 1Kb file.
