I can rip the full disc to my hard drive (as an ISO image or in folder/file format) using DVDFAB, but when I open it with "Shrink", its VTS (33, I think) is skipped in "Shrink". This has never happened before.
Try running the files through FixVTS and see if this helps. http://www.videohelp.com/tools/FixVTS
Development was stopped on the program in 2007, so it might not work on this movie, but can’t hurt to try.
Also ensure you have the latest DVDFab. Whenever I’ve had issues with DVDShrink, they were from a bad RIP.
