Director's Comm won't Turn On after IfoEdit

[chupara]

Hello everybody,

I like to strip Audio/Subs streams with IfoEdit.
Yet only recently, I've noticed that Director's Comments won't turn on after stripping the streams with IfoEdit.
I.e. the Director's Comments button is active/clickable, and it takes me to the movie, but the stream remains the same -- main movie soundtrack, not the Dir. Comm. track.
The Director's Comments stream is still there, and I could easily switch to it with a Remote (on a stand-alone) or with a click of the mouse (on the comp), and it would proceed with the movie to the end.

When I've noticed that, I did the following: after decrypting the movie (Monster-in-Law), I checked the Director's Comms -- it worked.
Then, after stripping languages and subtitles with IfoEdit v0.971 (retaining only English audio and Dir. Comms audio, and English Subs), I checked the Comments again -- it won't turn On.

How do I correct it?

Thank you all in advance for all the help I can get here.

[EDIT]Though the guides are old and working, I find myself doing the stream stripping with DVD Shrink instead.

Thank you, 2COOL

I’ve implemented the method described in you guide: it worked beautifully.
I’ve repaired several of my discs damaged by IfoEdit’s stripping.
Thank you.

So, IfoEdit is the culprit? – It leaves it kinda half-way after stripping, ain’t it?
Doesn’t finalize the job properly...

Maybe Derrow (this is the name of IfoEdit’s author?) could iron-out this little flaw for us? – like issuing a fix or, better yet, an updated version of IfoEdit?

Do you think he knows about this issue?
Or no one has dared approaching him with such a trifle?

— I’ve seen quite a few people on the forum struggling with this very issue.
Thus, the demand for an update is not only obvious, but appears to be long overdue.

I’m sure that was the reason which urged you to compile your guide on the topic: and I take off my hat for that before you, 2COOL!

Thank you from all the users like myself!
Great & very thorough job!
Thank you again.

But, when he goes away, he goes away for a long time. I'm sure he's preoccupied with higher priorities in his life. Would be happy to see him reply in this thread.

I was really into IfoEdit before PgcEdit came along and there are still functions with IfoEdit that are very useful. When I noticed this discrepancy, it was my plan to make the community be aware of it.

Can I strip Audoi/Subs with PgcEdit?
Would it have a VTS processed the way IfoEdit does: process all the VOBs of the VTS sequentially, change navigation accordingly, correct IFO, etc.?

Thank you.

I think stream stripping with VobBlanker or DVD Shrink/Recode works just fine and there's no need to correct the stream positions.

Hello everyone,

I’ve kept thinking: it couldn’t be so that we can’t just simply re-assign the number of the stream that Audio stream uses after stripping.

OK, the audio stream 3 becomes audio stream 2 after stripping, but instead of using stream 1, it continues using stream 2 (as before stripping).
Since stream 2 is no more, the Audio stream takes the default number zero (0) which is the movie Audio stream.
That’s why there is (seemingly) nothing happens when we hit Director’s Comms “On” button: sounds stays the movie audio.
Is it right? – please correct me if I’m wrong... but that’s how I understood the guide compiled by our respectable 2COOL.

Yet why can’t we simply re-assign the stream that is used by an Audio stream?
In our case, change it from 2 to 1?

Thence, I kept looking, and found out that we should find the register that provides the number, assigned to a particular stream.

In the movie “Guess Who?”, it’s located in VTSM 2, LU 1 (en), 6 (0:07) 64b
It’s in pre-command #10 and it reads: “Set gprm (4) = (mov) 2”

All that should be done is to change that 2 (after mov) into 1, so it becomes: “Set gprm (4) = (mov) 1”

That was the only digit I’ve changed, and the Director’s Comments snapped to normalcy again.

Thank you.

To do what you want, you must analyse the whole DVD, and understant which GPRM is used.

In very simple cases, the SetSTN commands in the DVD are directly using a numeric value. For example, the command "(SetSTN) Set Audio stream = 2" can be changed easily to use stream 1 instead of 2.

But in your case, the SetSTN command is indirect. GPRM 4 is used by the SetSTN command. A program should therefore verify all commands in the DVD to find where the GPRM is initialized. It's very difficult, because the same GPRM can be used anywhere for a totally different usage. It's relatively easy to figure out the line of code to change for an human, with the help of the PgcEdit's trace mode. But it's almost impossible for a program.

BTW, this is why DVD Shrink has an option to remap automatically the streams. It is able to fix the direct forms of the SetSTN command, but it leaves the indirect ones as they are.
