What does it mean when FixVTS says "Found VCID at LBA"?

For example, I get something like this running FixVTS 1.24beta on DVD Fab
Decrypter ripped files on the hard disk.
... Processing IFOs
... Writing IFOs
... Processing VOBs
... 98% processed (16.24 MB/s) -- 0:15 secs to go
... Found VCID 3/1 at LBA 187 (187 out)
... Done

I checked doom9 FixVTS web pages but this wasn't explained there.
.... http://forum.doom9.org/showthread.php?t=103452

The explanation wasn't on the VideoHelp FixVTS home pages either.
.... http://www.videohelp.com/~FixVTS/home.htm

Nor was any explanation on the AfterDawn FixVTS help pages.
.... http://www.afterdawn.com/software/video_software/dvd_tools/fitvts.cfm

Even a google search for "FixVTS Found VCID" turned up nothing usable.

Maybe only experts know what "Found VCID at LBA" means.
Are you such an expert?
Do you know what FixVTS "Found VCID at LBA" means?

I did manage to at least find out that VCID stood for "VCID (vob/cell ids)"
according to the FixVTS (http://www.videohelp.com/~FixVTS/Downloads.htm)
VideoHelp web pages (http://www.videohelp.com/~FixVTS/Features.htm).

There was nothing about this Found VCID message at DigitalDigest either.

Free-Codecs had a FixVTS explanation but I couldn't understand it.

Maybe someone who really understands DVDs can put this explanation into
plain english for me?

FixVTS opens a full Video Title Set (i.e. a menu vob, or a series of title
vobs) and updates a number of important pointers in the vob file.
Specifically, the forward pointers (enabling to quickly go from navpack to
navpack) and the two this->LBA pointers that indicate the sector of the
current navpack.
- In addition, FixVTS keeps track of all the navpacks, and of all the cells
in the vob file, and adjusts the IFO file for the titleset so that they
match what's in the vob files.
- FixVTS can also remove unreferenced cells (i.e. cells that are in the vob
files, but never played back, according to the IFO file).
- FixVTS also fixes blank packs that are sometimes introduces by DVD
rippers when they encounter unreadable sectors. These blank packs can
either be removed, or replaced by compliant "stuffing packs".
- FixVTS can be compared to an IFOEdit "Mock Strip" in the sense that it
performs some of the modifications that IFOEdit does. However, FixVTS does
not update all the pointers IFOEdit does, and does not mess up the PGC cell
flags or the cell commands. It does reorder the VCIDs, which is something
that a mock strip does not do. In addition, it is significantly faster
(in-place mode) and can process an entire DVD with 1 click.
- FixVTS tries hard to process as fast as possible by re-writing only
what's necessary. When processing from backup, everything must be
re-written, so that's the slowest option. When processing in-place, and if
the option to remove unreferenced material is not checked, only blank packs
and navpacks are re-written, and only if it's necessary (for example, if
some of the pointers are wrong, or if they are renumbered).

From this, can DVD experts say what "Found VCID at LBA" means in plain
english?
