Ok, guys, here I am again, causing trouble... ;)

See this thread (http://forum.doom9.org/showthread.php?t=98606) for more detail. Basically, Undertow, R1 has VobIDs that are completely unreferenced in some of its titlesets.

Normally, I have a pretty good idea of when this kind of material exists. First step in any of my DVD backup projects is to use future Doom9 DVD Hall of Famer Mr. Shrink's awesome DVD Backup Pre-Visualization utility, aka DVD Shrink v3.2. Unreferenced Material is itemized on it's opening scan.

Well, not this kind (not even after a full Analysis, btw). Seems these DVD authors are getting a little lazy these days and aren't properly notating their garbage material in VTS_C_ADT, I believe. Darn them!

I actually caught this on my first pre-run in DVD-RB. I noticed the unusually large third segment (it looked just like the first, only bigger) in VTS_01 in the Preview Editor and investigated it. Then my computer blue-screened, a day or two later goes by, and I missed it on my second run in DVD-RB. Darn me!

Anyways, I was wondering if it's possible for DVD-RB to highlight this on the front-end of its workflow? It certainly does on the back end (i.e., WARNING: VOB Count Old: x New: y). That's when the light bulb went off again.

Well, I figure it's worth a try. Even if it goes into that pile marked "Things I'll never get to", at least it's a start??! ;)


p.s. - I think jdobbs and a bunch of you other guys are headed for Doom9's DVD Hall of Fame as well, btw... :)

Ok, a couple of things / updates.

Not surprisingly, the references to this "Unreferenced" Unreferenced Material were restored (in *_C_ADT, and possibly elsewhere) when DVD Rebuilder reauthored this project. They thus became visible in DVD Shrink again.

I don't know if this suggestion has ever come up, but I wonder if there would be some benefit to the Preview / Blanking function if you could do this by title. There are a lot of times when this is how I would like to blank (and would be faster, too). I know, definitely more tedious to code. Blanking by title would probably make this kind of material much more visible. Regardless, I don't think anyone would want to sacrifice the flexibility one has with the present VobID / Cell blanking functionality.

Lastly, I did some work on this phenomenon, this "Unreferenced Material" of the "Unreferenced" kind. It's due to changes Lightning UK! made to DVD Decrypter back in March.

I've posted more information on this here (http://forum.doom9.org/showthread.php?t=98862)...
