Remove a bad VOBID

[Rasta]

I use DVD Shrink to remove the main movie and to remove the episodes of an episodic DVD. The problem with this is that DVD Shrink always creates an unnecessary or corrupt (I don't know which but the the movie is fine without it) last VOBID, it actually makes a VOBID that is pretty much pointless right after the VOBID which contains the end credits. This last VOBID corrupts every program that tries to process it, namely DVD Rebuilder. What I would like to do is to remove this last VOBID, on Episodic DVDs it makes this bad VOBID on the last VOB of each titleset.

I want to remove this VOBID without comprising the DVD structure, I tried just using VOBRator and saving the last VOB without including the last VOBID which obviously does not work. I can use IfoEdit ok to accomplish this EXCEPT on episodic dvds. My question is how can I remove the bad vobids without hurting the structure so I can use DVD Rebuilder on it or do other things? Is it impossible to re-author multiple vts with ifoedit, i think so but just checking? Thanks.

I'm not sure how to find that information in IfoEdit but maybe this will help. In every VOB it is only VOBID 1 which is really a video. In each of the last VOBs in every titleset (VTS_0x_02.VOB) there is a VOBID 2, which is not present in VTS_0x_01.VOB, which is the bad VOB. So basically, I want to get rid of every VOBID 2, which like I said occurs in every other VOB. Its weird, I don't know why Shrink does it but Shrink is the best program, aside from this problem, I have found to remove episodes. If anyone can help I'd appreciate it, and if I need to post IfoEdit output I will if you can tell me what you need. Thanks a lot everyone.

This last VOBID corrupts every program that tries to process it, namely DVD Rebuilder. Upon analyzing your original and DVD Shrink files, it looks to me that DVD Shrink is doing what it supposed to do when reauthoring. Your original VTS_01 had 4 PGCs = 4 Titles = 4 episodes. Reauthoring with DVD Shrink works by putting your 4 Titles into individual VTSs, VTS_01 to VTS_04. Though it has to renumber your VOB and Cell IDs, it shouldn't make a difference in play. The cells are the same before and after for all your episodes.

What I would like to do is to remove this last VOBID, on Episodic DVDs it makes this bad VOBID on the last VOB of each titleset.All your episodes,pretty much, has the same layout with 7 chapters each. What they all had in common was a last cell with 15 frames of blank.
[Ch 07] [Pg 07] [Cell 07] [V/C Id: 2/ 1] Layer Br.: time: 00:00:00.15 / 30 fps
It is common practice to have this short blank segment at the end so that you can use your chapter skip button to go to the next Title/episode. This is not a bad thing. In your case, you wouldn't be able to chapter skip when Chapter 6 is playing if you didn't have it. Of course, Fast forwarding works but it's a nuisance if chapter is too long. If you choose to remove it, it's easy to do with IfoEdit since that last cell has it's own VOB-ID. Just use VOB Extras,select Strip VOB IDs, and uncheck VOB-ID 2 on the stream list.

My question is how can I remove the bad vobids without hurting the structure so I can use DVD Rebuilder on it or do other things?Now, I don't see how this last cell, V/C ID 2/1, has anything to do with your corrupting your DVD. DVD Rebuilder should be able to process this without problems. Maybe I'll have to do a test run with a episodic DVD myself to check this out.

Edit: I'm assuming that the last cell is just a blank, right? Or is it something else? Also, were you using DVD RB 0.57?

hm, well that's interesting. However, stripping with IfoEdit works if its not an episodic DVD, but with the episodic DVD there is more than one VTS. How can I use IfoEdit's VOB Extra's features to strip just VOBID 1 without creating a DVD with only that VTS, btw if I do this IfoEdit actually complains about some file size difference in Endsector or some such. Also, it will screw up DVD Rebuilder, every single time. The only way to make DVD Rebuilder work correctly with the DVD Shrink output is to remove the last VOBID that is blank or whatever it is. Well, I guess I just need to figure out how to use IfoEdit to do this or some other way. I have re-authored with IfoEdit before, and like I said, this method is fine for a single VTS but with an episodic DVD ... well if it can be done I need a little more help. Thanks a lot for all the help you've given so far though.

btw if I do this IfoEdit actually complains about some file size difference in Endsector or some such.You need to do a Get VTS Sectors in IfoEdit afterwards.

Maybe missing this post step is whats messing your DVD up.

Oh I though when you checked a VOBID in the "strip" menu that meant you retained it and did not retain the other stuff. Also, I should add that when I do try to "strip" the only option is VOBID 1, even though the second VOB of each titleset contains the VOBID 2. Doing this also makes the VOB (like VTS_01_1.VOB for example) 670MB big when it was previously .99GB. This is weird to me as the whole VOB is supposedly only VOBID 1. I get the "file size difference" error when I do Get VTS sectors, so I don't know. There must be a way to do this. It seems like if IfoEdit did multiple titlesets, or if there was some way around this other than convoluting the VOBs by joining them, it would all work.

I just did it again. It looks like the "strip" method doesn't do anything other than to make the first VOB in each titleset smaller by about 300 megs, I don't really know what it's doing. The VOBID 2 is still there, I think this is because IfoEdit didn't even give the option to "strip," or whatever, VOBID 2, only 1 was in the menu. hm...

But, when I do the same with your original IFO, the last VOB-ID is present. VOB-ID 5. Maybe you should start over again and strip from your originals and then use DVD Shrink. Or maybe do another reauthoring without stripping. Perhaps, DVD Shrink glitch the first time around.

Don't know why VOB-ID 2 in your DVD Shrink files is not showing but then again I don't have the VOBs to check.

[Rasta]

Ya, its pretty weird. There must be a way to do this. I'm sure I could just strip from the original but that would make all the episodes in one titleset, where episodes could share a VOB which would make for kind of a nightmare sorting out. Also, Shrink removes the "layer break," I'm just worried about the potential problems stripping from the original. For regular movies I can just strip, actually I have to run IfoEdit twice to be able to get rid of the problematic VOBID but that's another issue which I can deal with, so it would seem I could use the same theory for episodic discs. The only holdup is that IfoEdit doesn't seem to handle multiple titlesets, although it is a great program. I've tried VOBRator and some other stuff to remove the bad VOBID but those methods don't work, at least the way I do it.

aha, slowly but surely I am getting to the bottom of this, yes obviously I'm a newbie. The VOBIDs that I keep talking about giving me problems is the LAYER BREAK. I want to remove that. I have DVD Shrink 3.2.0.15 set up to remove the layer break but whenver I look at the IFOs of the output the layer break is still there, the VOBID it references is indeed a .15sec thing. It is the source of the all the problems, so what can I do, and why is it that DVD Shrink is still retaining it? Or is Shirnk doing what its supposed to do but maybe something I don't understand is happening? (and yes, in the IFO of the Shrink Output it does indeed say "Layer Break" for the last chapter). Thanks everyone for any help.
*Rasta

--edit-- I guess what I want to do is remove the last chapter of each title, which only contains V/C: 2/1 and remove all references to that vobid from the IFO. After that can I used VOBRator to "resave" the VOB without the last VOBID? Or what is the best/correct thing to do? Thanks

Or what is the best/correct thing to do? The most logical thing to do, IMO, is to strip the last cell (V/C ID 5/1) in your original files first. Since IfoEdit only works on one VTS at a time when stripping, why go through the time to strip 4 VTSs after DVD Shrink reauthoring. All your 4 episodes are in one VTS in the first places in separate PGCs.

Again, I've done alot of episodic DVDs with layer breaks in them and had no problems with playing DVD Shrink files. As for layer breaks, they're really not needed when backing up to a DVD-5.

[Rasta]

Well, I thought about that ... Ok, then how do you go about doing that because when I select VTS_01_0.IFO of the original and do a strip, and choose all but VOBID 5, I get some problems. First, after it is finished and you click "ok" on "Finished VOBU pointers" you get erros like "Endsector doesn't match" and it tries to use VTS_02_xx.ifo for some reason, I though it only did one titleset. And the BIGGEST problem with that is it makes all the episodes in ONE PGC, with like 24 chapters. I definitely don't want that. I'd like to either have one title with 4 PGCs or 4 titles, it seems more work to try to seperate the chapters ... Well if you could give me an idea of how to use IfoEdit to do what you suggested I'd appreciate it.

And the BIGGEST problem with that is it makes all the episodes in ONE PGC, with like 24 chapters. I definitely don't want that. What options have you checked? You should have only these checked

Options
X Strip VobID’s
X Correct Vob-Unit (Navigation Pack) pointers in VOB-files
X Correct original IFO files

VOB Expert Options
X Remove P-UOps
X Remove Macrovision
X Adjust Vob-Unit pointers
X Adjust Audio/Subp point.

thanks. As far as the VTS_02_xx thing, don't worry about it, I hit "get sectors" when I shouldn't have. Those are the same boxes I had checked except I had also "create new IFO." I am trying it out without that one checkmark. Thanks for your help.

BTW, have you done Get VTS Sectors with IfoEdit and then reauthor with DVD Shrink?

[kheops]

this thread is pretty old :(

i have exactly the same problem, i'd like to remove the vobid 1 to keep the 2 (main movie) but only the 1st shows up in ifoedit

when i try to get vts sectors, ifoedit complains about a missing file and freezes

2COOL if you want some details just ask i'll try to do my best

:)

@kheops

Using IfoEdit, go to your VTS_C_ADT table and change the following value to 2.


OLD> Number of VOB IDs in VTS_VOBs 1
NEW> Number of VOB IDs in VTS_VOBs 2

Now you should see your all your VOB-Ids in VOB Extras. ;)

[kheops]

thanks a million 2COOL it worked :D

small things i'd like to add :

dvdshrink gave me exactly the same files so it wasn't the solution
of course now the layer breaks are gone and i feel the new ifos much proper

of course ifoedit can't verify everything, but it might be a good idea to open a box saying "hey man your Number of VOB IDs in VTS_C_ADT isn't good do you want me to correct it ?" :)

thanks again

I have followed this interesting discussion.
After a quick test, I can confirm the bug in DVDShrink.

And now, the good news: I have added a check for this situation in PgcEdit. Now, when you load the DVD, a warning will popup to inform the user, and the table will be automatically fixed. Therefore, all you have to do to fix the number of VOB IDs in the VTS_C_ADT table, is to load the DVD in PgcEdit (v0.4.7 or more) and save it back.

PgcEdit v0.4.7 will be released soon.
