DVDshrink gives the following error message when "full disk" is selected: DVDshrink encountered an error and cannot continue. Invalid DVD navigation structure.
DVDshrink gives the following information when "re-author" is selected:
Name: VTS 1 Duration 00:03.45 Size: 95 MB
Name: Title 1 Duration 01:33.34 Size: 4,255 MB
There is no more information. Selecting Title 1, image and sound can be played starting at the beginning of the DVD. I see no way to cut at any point nor to copy or save a cut-out section.
