Gaps in iso mode and question about movie only mode

[sneaker_ger]

Hi there,

jdobbs, what do you think about a feature that adds 32k gaps between ifo and bup files like it is recommended in this thread (http://www.videohelp.com/~r0lZ/pgcedit/third_party/blutach/Burning%20With%20PgcEdit.htm) - it can be done with PgcEdit and ImgTools Classic already and now that dvd-rb supports iso-writing it would be nice if it would support that.
I would also like to set the standard subtitle(and activate it) and audio in movie-only mode.

One question about movie-only: While DVDShrink writes the following line into the first title in the reauthored ifo, DVD-RB doesn't:
Set gprm(0) =(mov) 0
What does this line do?

[lark]

well, it just load the value 0 to register 0.
if no-one is reading the register, it has really no meaning.
on the other hand, registers are (should be) initialized to 0, when a disk is loaded => again, this has no meaning (well, some exceptions).

where is it set (by shrink)? in 1st play or in menu or in the movie pgc?

It's in the pre-commands of the first title of a DVD reauthored with only keeping the main movie.
What are the exceptions you are talking of? I barely know anything about that ifo stuff.


And what about choosing standard audio stream and standard subtitle?

[lark]

as said, if no-one is reading the gprm0, there's no point in setting it either.
since we are speaking about movie only, the reader should be in the movie's PGC or in the 1st play...

the execption, i was talking about, was for the 1st play case. normally you don't get there any more once the disk has been 1st loaded, but it's possible to add a command to jump there.

about the audio and subs, you need to add commands to select them.
i think 1st audio is selected by default, but if you want to set subs on, you need a command for that. (and also, if you don't want to have the 1st audio as default).
RB doesn't add those commands and imho neither does shrink.
i'd suggest you to try pgcedit.

Hi there,

What does this line do? Just my own opinion -- but it's another solution looking for a problem... Adding the 32k gaps does nothing except in the unique event that you have a VOB set that is less than 32k long and the IFO gets somehow destroyed, making the system resort to the BUP...

The odds of a VOB set being that short and still being referenced is extremely low -- and the odds that the IFO gets corrupted is very uncommon, so the combined chances of needing the 32k gaps is astronomically low...

Bottom line: I've never known of this ever happening to anyone, ever... so why go out of my way recalculating sector offsets?

@lark
thanks for clearing that up


DVDShrink has the feature to select standard audio and subtitle stream (and activate the subtitle).

About the gaps: I thought that these gaps have to be there for compliance. But I do not have a source for that so I am probably wrong with it. But if it is not too much work - why not add those gaps just to be sure? I think the gap between a ifo and its bup is always less than 32k in movie-only mode like in DVDShrink, isn't it?

The reason why I would like to see these two features in DVD-Rebuilder is that if it had them, I did not need PGCEdit anymore when ripping a DVD and could do the whole process in one click.

[jdobbs]

Only if your entire movie is less than 32k... :sly: Have you ever seen a 32k movie? On a DVD the IFO and BUP are put at the beginning and end of the VTS with the entire set of VOBs between them.

You can do it in one click now.... you don't need PGCEdit. Your adding work for yourself for no reason I can see.

DVD Rebuilder outputs compliant discs.

[sneaker_ger]

But Discs reauthored with DVDShrink for example don't have a VOB between the VIDEO_TS.IFO and the VIDEO_TS.BUP?
The thread (http://forum.digital-digest.com/showthread.php?s=&postid=222578#) where I read about those gaps says that NO DISC reauthored by DVDShrink has all the gaps "needed".

That does not match with what you say? :confused:

I am repeating myself, but do you plan adding a standard subtitle and standard audio stream activation - otherwise the users still have to activate them with PGCEdit for movies with speech in forgein languages?

[jdobbs]

Show me in the spec where it is "needed"... and I'll add it.

[edit] Never mind... it's easier to add it then to argue about it... and it won't hurt anything.

[sneaker_ger]

Thanks :) It's really great how much work you put into DVD-RB.
Now I will be able to sleep better after burning DVDs...


And what do you think about choosing standard subtitle and audio stream?

That's the spirit. :D

That's the spirit. :D
... as long as you don't do that too many times lol
