Starter For 10, R1. DVD structure changed, titlesets reduced / remapped?

[JFerguson]

The Setup:


Source was Starter For 10 ripped via ImgBurn v2.4.0.0 (Mode, Read). AnyDVD v6.3.1.7 was enabled on source DVD-ROM drive during ripping with all Feature Removal options enables with the exception of "PC-Friendly (Autorun on Video DVD)". ISO image file was mounted via Daemon Tools v3.47.
No preprocessing was performed.
DVD Rebuilder Professional Edition v1.27.2



The Anomaly:

DVD-RB produced a titleset/title structure that differed from the original. VTS_01 was removed from the original structure and the number of titlesets was thus reduced by one.

Comments/Thoughts:

I have never seen this happen before. Is this expected behavior? Here's a small dump of the DVD structures:

Original:
Number of Title Play Maps: 5 (VMG_PTT_SRPT)
Title 1: VTS_01_*, TTN_1 (Angles: 1) (Chapters: 1) (Start Sector 9944)
Title 2: VTS_02_*, TTN_1 (Angles: 1) (Chapters: 13) (Start Sector 97103)
Title 3: VTS_02_*, TTN_2 (Angles: 1) (Chapters: 1) (Start Sector 97103)
Title 4: VTS_02_*, TTN_3 (Angles: 1) (Chapters: 1) (Start Sector 97103)
Title 5: VTS_03_*, TTN_1 (Angles: 1) (Chapters: 2) (Start Sector 2585685)

Number of Video Title Sets on this DVD: 3


DVD-RB Output:

Number of Video Title Sets on this DVD: 3


DVD-RB's Video Manager stills says there are 3 titlesets, but it only built 2, shifting the original titlesets 2-3 down to titlesets 1-2.

Anything odd about the original DVD structure? No, I don't think so -- there's one title in VTS_01 at 8192 bytes and menu data at 170MB.

In my project:

vts_min_size=1024
vtsm_min_size=1024

and VTS_01 was not processed by DVD-RB.

Just wondering what might be going on here.

Thanks...

You say no preprocessing but in reality your ripper has done a stack of it ("all feature removal enabled").

Nonetheless, it does look strange. Is VTS_01 referenced or is it a fake VTS?

Hi!all Feature Removal options enables with the exception of "PC-Friendly (Autorun on Video DVD)Your post is somewhat unclear in this regard. If the "PC Friendly" did, in fact, start automatically when you loaded the DVD, this may have caused the strange behavior.

Re-rip the DVD and try holding down the "Shift" key throughout the initial loading...

It's probably an unreferenced VTS that was removed. Have you tested the disc? If it works -- then don't worry about it.

Well, preprocessing in the traditional regard (e.g. title blanking in VobBlanker). I don't think RC/RCE and macrovision removal, etc. are culprits.

None of the at-a-glance tools (Shrink, VobBlanker) are indicating anything unreferenced or abnormal with the titleset. With PgcEdit, when I backtrace Title 1 (the only title in VTS_01, and basically a NOP/jump back to VMGM), it's called by Menu 3, which is called by Menu 2, which is called by the Root Menu. And backtrace of the Root menu in VTS_01 backtraces to "Callable with remote control RootMenu button".

This titleset basically contains trailers (the menus) which apparently aren't referenced/accessed by anything other than the remote... is this unreferenced, then?

[jdobbs]

Yes -- and if true it should be removed. Normally what you'll see in something like that are repeats of other titles or just junk (like long streams of blank frames).

To see if they are referenced, do a Find Uncalled PGCs in PgcEdit. You may actually be able to delete whole titlesets.

Ok, did so. The whole titleset came up highlighted -- that explains it. Thanks for the tips...
