Ok, I'm backing up a DVD, and I'm going to keep some, but not all extras. This is my procedure:
1. Load DVD into whatever tool (Shrink, PowerDVD) and determine which
titles to keep.
Titles (VTSs): 1,4-10,15 (5,4,1)
2. Run DVD-RB and load DVD. Note which VTSs are/are not available
for processing and/or blanking (PRO version). Exit DVD-RB.
VTSs available: 03-07
VTSs not available: 01-02
Note: V02 is not available for processing / blanking, so this must
be taken into account in next step. It's not in my keep list, and
I missed this and lost 26MB on this run.
3. Determine total post-processing gain (TG). Be sure to take into
account VTSs which are not available for processing in DVD-RB. I
use Shrink; using [original size - shrunk size]:
Menus= 116 - 58 = 58MB
VTSs not available = 27 - 1 (Still Image) = 26MB
Total Gain (TG) = 84MB
4. Determine TargetSectors setting. I like an end result of 4460MB.
I believe the default setting is 2236400, producing an end result
of 4.32GB. We realize a gain (TG) from post-processing, so our
actual end result (AER) should be greater than our desired end
result (DER). A simple ratio calculation will give us the
TargetSectors (TS) setting. So:
AER = DER + TG = 4460 + 84 = 4544MB = 4.4375GB
Targetsectors = AER / TS = 4.32 / 2236400
= 4.4375 / TS = 4.32 / 2236400
= 2297230 (rounded to nearest 10)
5. Open rebuilder.ini file and add TargetSectors setting:
[Options]
TargetSectors=2297230
.

6. Run DVD-RB and load DVD. Make selections and options. For me:
V05 = -a2-a3,s2 (i.e., deselect audio, subtitle track(s) 2,3 and 2)
Steal Space from Extras = 50%
Movie matrix = Encoder Default
Extras matrix = Low Bitrate
CCE options left at default = 25 / 16 / 2 (Bias / Prec / Passes)
7. Hit Prepare. When finished, go into Preview/Edit and perform
blanking. Don't like the numbers? Adjust settings and repeat. For
this example, I changed the Steal Space from Extras to 33%,
gaining 400kb in the Extras bitrate at a cost of 50kb to the Movie
bitrate (determined by examining before/after .ECL file). Return
to Preview/Edit feature and repeat blanking, due to re-Prepare.
8. Make other adjustments to project. I opened the REBUILDER.ECL
file in notepad.exe and changed vbr_pass=2 for the extras VTSs.
9. Run DVD-RB build process. Select "Skip PREPARE Phase in Batch"
option from menu and save project. Add project to Batch
processing and Start.
10. When complete, load project into Shrink and post-process. My
actual end result here was 4.41GB, which reflects my initial TG
calculation of 58MB (remember, the missed 26MB) and that hit it
right on the nose.
That's it. So, is there anything I could do to make this easier? Thanks...
