Ran an experiment with DVD-RB v1.00RC2. Wanted to see if I could get it to compress extras only on a 2 VTS set. V01 = main movie. V02 = extras. Here's what I did.
1) Nuked V01 with PgcEdit.
2) Set TargetSectors = 129420. Wanted 256MB final size (which included 75MB of menus). So, from the default TargetSectors setting of 2236400 (giving 4.32GB), I did:
256/1024 * 1/4.32 * 2236400 = 129420 (rounded, nearest 10)
3) Ran DVD-RB. It produced 256MB output right on the dot.
4) Loaded output into PowerDVD, played extras, no audio.
5) Loaded output into DVD Shrink, V02 audio streams are gone.
I was wondering if anyone might know why my audio streams were nuked?
Ok, so I got the audio back. Here's what I did:
1) Ran DVD-RB against original DVD with some arbitrary TargetSectors setting (2276500, to be exact).
2) Output from this run plays fine, all audio is fine.
3) Took my V02 output from bastardized run above and copied it into this run's D2VAVS directory.
4) Reran Rebuild stage for this run.
5) Output is built, with my V02 output from bastardized run, and audio is fine. V02 output is +17MB larger than bastardized run, which equals the original missing audio size (and verified in DVD Shrink, V02 audio = 17MB).
So, I got the audio back, in a roundabout kind of way, and I am trying to figure out what this means - i.e. why the difference in behavior when building V02 output from these two runs?
Appreciate any input - thanks...
