    I converted camcorder tapes to dvd on a standalone. I then edited and chapterized in MyDVD. They play fine but some won't disk copy for backup... I guess they copy process is supersensitive to tiny scratches.

    I try to use DVDShrink to do the backup even though they aren't encrypted and don't have to be shrunk... It is a good way to get an ISO file for burning with Imgbrn. BUT

    I get the message Invalid Navigation structure. Why would this be. Am I going to the trouble of backing this all up for the future and ending up having disks that aren't going to do well do to some strange navigation structure?

    See if Nerovision Express (part of the Nero suite) will import those disks for you. Nero has a 30-day fully functional free trial. You can also try TMPGEnc Author 1.6 which has a fully functional 30-day trial.

    DVD Shrink is extremely sensitive to DVD navigation. There is likely something in MyDVD authoring causing Shrink to cough it back up.
