Ripped it with AnyDVD/DVD Dycrypter combo, no problems. I made a full backup with CloneDVD and it seemed absolutely fine. Made a Main feature backup and that's where the fun began. Got a backup with interviews and extras mixed in. Opened the file in Vobblanker and ran it through that then opened in Shrink and saw the problem.
There are indeed 2 main features (what a waste of real estate) one that has the garbage and one without. I just picked the good one and backed it up with Shrink (no compression needed).
If you use Shrink and take the garbage one out (replace with image) you should have plenty of room for a full backup including extras with little or no compression.
