Just what 300bowler said.
1. What are PGCs and what do they do?
PGC's are small sections of a movie or trailor preview.
2. What does the Blank function actually do to PGCs?
The BLANK function basically eliminates entire titles or selected PGC's. The KEEP function keeps and the BLANK function eliminates.

That's not what I want. I want to fix DVDs that have been corrupted by read error in the decrypting process. This bad data evidently produce a memory error when the are used to calculated memory address.
I had this odd experience.
1. DVDShrink died with a vague message analyzing a DVD.
2. I ran FixVTS on the whole DVD.
3. DVDShrink had a read error in VOB_1_01.
4. I killed DVDShrink.
5. I ran DVDShrink on DVD again so I could get the error message to post here. But it was successful.
6. The output ISO was too big as I was warned.
7. I used DVDFabDecrypter to read in the ISO to DVDX.
8. DVDShrink had a read error in VOB_1_01 on DVDX.
9. I ran DVDX through FixVTS and VOBblanker.
10. DVDShrink again had a read error in VOB_1_01 on DVDX.
11. I killed DVDShrink.
12. I ran DVDShrink on DVDX again. But it was successful.
13. The output ISO written to media seems fine.
That's odd behavior.
I'm an experienced programmer. This feels like DVDShrink has some uninitialized variable that starts with random values, so sometimes it works, sometimes it doesn't running the same data.

I just did this same procedure on another DVD that read in badly. It seems like if DVDShrink bombs in Analysis, it takes up from where it left off when you try it again. This probably doesn't work if it bombs during Encoding.
Such behavior could easily be built in DVDShrink with a Continue? option whenever an error is found.
I have 3 more "bad" DVDs I will try this on.

twidlar,
If all of the programs you tried have bombed out then you have to have a disk that is either a bad mastering press or the scratches are really bad and nothing will read through those scratches. Have you tried to find a better copy of that movie?

Only DVDShrink is bombing out. When it bombs out in the Analysis phase, it will resume from where it left off. For one DVD I "fixed", I had to restart 12 times. But the result played without a problem or noticeable artifact.
I was unable to get hold of another copy of the DVDs I was having trouble with. The problems were very likely read errors resulting from scratches. The programmer in me tells me that unless the resulting data is totally garbled, it should be possible to drop the few frames having the problem (maybe replacing them with the last good frame) and get a playable result.

Will CloneDVD handle DVDs that have corrupted data?

I have no idea if it handles corrupted data but I would try it as you only need this disk copied. If this was a home movie then I would use Premiere to edit out the bad areas but those files are .avi and what a DVD is is .vob, bup, and ifo files

The DVD for which I had to restart DVDShrink 12 times (for the Analysis to continue from the point where it bombed) play all right except for three spots where the picture breaks up some for about three seconds. Not perfect, but very usable.
I have recovered the Spinal Tap I was having trouble with. I had to restart once.
