A side effect blanking titles...

jsoto · 24th February 2005, 00:07

Hi all,

In the last versions of VobBlanker (and IIRC, also in pgcEdit) audio and subs status are reset to zero in blanked PGCs, because seems this is the right choice.

Well, this is the second time I've found this problem, so I'd like to share it. This is the situation: One VTS with the main movie (say PGC 1) and an intro (say PGC2)

When playing the DVD, you can select in the menu your favourite audio/subs but when you selects "play" the DVD plays first the intro (which is blanked, can be with pre to post trick done or not, it is the same) and after, the main movie.
The result is that your audio/subs selection is lost, and reset to the first one. (I've tested this in PowerDVD and WinDVD, but not in my settop)

Recovering the original status of the audios, (with a blank cell instead of PGC 2) powerDVD and WinDVD keep the audio selection..

So, the only solution I can imagine is to add a checkbox to reset or not the audio/subs status in blanked PGCs.

BTW, deleting playback of PGC 2, I got the same situation

Hummm. Ennoying!

I'll would like to test this further, but for now I'm verry busy. (Installing a new PC is horrible!)

I think right now at a possible solutiion: copy the contents of the substreams SPRMs, and force them back later. May be difficult to do, though...

Anyway, thanks for the info.

An alternative (and easier) solution is to add one audio pack (silence) at the end of the blank cell per each "deleted" stream. The blank cell we are using is 5 packs size (one nav and four video), so adding two or three packs (one per audio) is not too much...

Anyway, why do we have to clear the audio status when blanking? May be because Phillips verifier complains? Phillips complains about almost everything you can imagine... even in originals.

From the changelog: I've added this "bugfix" (clear audio/subs status)in VB 1.5.0.8 (09-11-2004), but AFAIK nobody had a problem with it in the previous versions.

That's THE question. And it's what I want to test.

IMHO, the 'real' standard is what the players are able to do, not really what they are supposed to do.

Hi jsoto,

I don't understand much of the technical aspects your addressing, but I have a simple question I think is related.

When using VobBlanker, should I check the boxes for 'Clear audio/subs status' or not? The default setting is unchecked.

TuRiSOft · 16th December 2005, 21:29

I've never experienced this issue because , I think , i ever use to blank intros and then I use to use the "Jump to PGC upon DVD Insert" Macro in PGCEdit , so the intro is never played !!!

jsoto · 16th December 2005, 23:27

I never check them. I know its not fully standard, but they are lots of originals with the same non-standard "issue". And I do not know any settop which complains.

@jsoto

Is this the same as PgcEdit's "Fix number of streams in VMGM/VTSI_MAT tables"?

Regards

jsoto · 17th December 2005, 11:03

No, it is'nt.

PgcEdit's macro checks the coherence between the data stored in the PGC tables of the IFO versus the general domain tables VMGI/VTS_MAT, but pgcEdit does not explore the VOB files to see if the audio/subs tracks are really there.

VobBlanker's stream status reset is done (if checked) when the PGC is blanked, that is, no audio and no subs will be in the VOB file in this PGC.

I didn't check it, but probably if you delete the PGC in VB (or kill playback, removing the cells in pgcEdit) the issue will not appear... In any case these two options are not allowed in Titles domain.

I notice the default setting for "Clear audio/subs status when blanking/stilling" is now checked.

Is the problem resolved?

blutach · 8th October 2006, 14:48

Tom,

If your player doesn't experience a problem, leave this checked. It is a convenience, especially for cycling with remotes.

Regards

jsoto · 10th October 2006, 01:27

Also, it's a very good idea to use "Jump to PGC upon DVD Insert" always....You'll avoid the potential problem in any settop and the settop will go as fast as possible to the wanted PGC (menu or title) w/o playing blank cells or going across a lot of IFO files...

Hmmm, I can't even find that option. Is it somewhere other than in "More Settings?"

Also, I just realized the default for "Clear audio/subs status when blanking/stilling" under "Menu PFCs" is checked, but there is another option for "Clear audio/subs status when blanking/stripping" under "Title PGCs" which is unchecked by default. I guess I'll just leave them both as is. I don't understand what the difference between blanking and stripping is. I think I usually "blank."

It's in PgcEdit - see guide on site.

Blanking = making a piece of video into a small blank
Stripping = deleting unwanted audio and subpicture streams
