Pardon me if this is the wrong area but it's been a while. I'm running the latest DVD Shrink and I pop in the dvd and I get a message stating: "...Invalid DVD navigation structure." I tried it on two different machines...same thing. It does not even open the disc. I'm suspecting a disc that cannot be copied...any ideas..?? Thanks.
That means your disc has protection on it that Shrink cannot read. Using RipIt4Me or DVDFab Decrypter should work.
