invalid navigation structure ??

[guilhas]

i made a DVD with NeroRecode and burn it into the imagedriver, then burn a DVD midia that could not be read in standalone DVDs and even in my DVD-RAM. Anyway i got the imagedriver, i try to copy it using shrink and/or decripter, both programs give me the error
'Invalid navigation structure'

any ideas of how to solv this navigation structure and burn another DVD ?

thanks in advance!

First try cleaning the original DVD with warm soapy water (Dry THROUGHLY). Are you indeed trying to backup a commercial DVD?

Then it is probably most likely a media compatibility problem.
