IFOedit

[berrick]

Hi All,

Hears hoping sum1 can tell me wot i do wrong!!

I have followed the guides on this site for stripping out unwanted audio and menu's from a dvd. I also dumped all the extra's. I then used menuedit to remove dead links on menu's, then tried to burn to DVD. With no luck due to errors.....

All the problems appear to be due to the fact that video_ts.vob has an entry for VTS_02_0 which i have deleted as it only contained the extra's.

So the question is how do i get rip of this entry.

Thnxs in advance
Berrick

Do you deleted the VOB file manually? You may not do that!
IfoEdit don't let you remove the VOB file completely: you must keep at least one VOB ID.

But you can use PgcEdit to remove a menu VOB completely: PgcEdit will also remove all references to the VOB in the IFOs.
Use the "Blank Out all PGCS in Domain" function (or "Blank Out all menu PGCs" in the left pane context menu), then select the radiobutton "Completely remove the menu VOB file".
Good luck!

Thnxs for the reply's.....

i have found that dvd shrink cant open the dvd i am modifying after i have removed the forgien menus. I followed the ifoedit guide..... so for now i'm going start again.

BUT i'll be back :) cause i'm sure to have questions

[berrick]

DA DAAAAAAAAAAA!

I have now gone thru the process again (and as i woz a little more awake) i decided to read the guide all the way to the end even tho i didnt need to re encode the main movie and releazied i hadnt clicked on the "get VTS sectors" button.

I assume that this is a must even tho everything played correctly in power dvd!! NEway i clicked it and it correct some files.

The last bit which i couldnt work out was the correct way to remove the extra's contained in the second title set in the second vts file (vts_02) using IFoedit, which in my sleepy clumsy way is what i tried to ask in the first of these posts :D

But to cut the story short i cheated and reripped my modified movie using smart ripper, telling it to drop vts_02. Then when i went to burn the result to disk using nero 6 I just set the time and date to the current time and date for good messure and it worked!!

I appricate the reply's and would still be gratefull if some1 can explain how to use ifoedit to do what i used smart ripper to do

Thnxs again

You might get play errors, unless you convert your all your Post commands to Pre Commands for VTS in question. The more safe and logical thing to do,IMO, is to blank the whole unwanted VTS out instead.

Here's a PgcEdit guide on How to Completely Blank Out a Titleset (VTS) (http://forum.doom9.org/showthread.php?s=&threadid=81112). ;)

thnxs 2cool... i will lookin to this on my next project l8r this week.... a couple of questions if i may.

1 - how/where can i check to see if the post commands have been changed to pre commands?

2 - would this not have bin dun using smart ripper, telling it to rip movie and keep menus therefore not ripping the offending vts?

3 - By using this guide and totally blanking the vts concerned i assume this is removing the entries for it in the video_ts.vob and therefore i can then delete the relevant vts files

Thnxs once again

In PgcEdit, it's referred to as the "Kill PGC Playback" feature. This is pretty much the second part of Blanking all Titles part. Look in the command section for changes.

2 - would this not have bin dun using smart ripper, telling it to rip movie and keep menus therefore not ripping the offending vts?No and no other ripper will do it all if you are referring to Pre Command conversion. Also, Smartripper has ceased in development years ago. DVD Decrypter is the top-used ripper by it still being updated and added with new features. ;)

3 - By using this guide and totally blanking the vts concerned i assume this is removing the entries for it in the video_ts.vob and therefore i can then delete the relevant vts filesVIDEO_TS.VOB is a menu VOB and so is all VTS_##_0.VOBs. PgcEdit can also blank out menu vobs (VMGM and VTSM) too along with Title VOBs (VTST). The VOBs in question are replaced by a single blank, Post Commands converted,and the associated IFO edited to reflect changes. Honestly, I never do any deletion of files. Well, with the exception of menu VOBs of 0K. If it's a VOB, I blank it out.

[berrick]

oooooooooo! my brain hurts :) that manual guide will need a few reads.. but i think its worth it as u took the trouble to post it AND i hope it will give me a better understanding of wots going on.

would u clarify a point - when u say blank are u meaning that the vob file stays but its file size is reduced to zero... as my reasons for getting rid of certian vobs is to reduce the total size of the dvd... but then u nu that ;)

Cheers

They should have been all REPLACED by a single 10 KB blank VOB. You will notice a decrease in DVD size because of this. This blank VOB will never be 0 KB but hey, 10 KB is still next to nothing.

[berrick]

VERY tru.....

well thing are going along nicely, learning lots nad having fun.. just need to work out why the menus work in powerdvd but not properly in stand alone after using menuedit. Who would have thought a little silver disk could require so much understanding in wot make it work :)

Totally removing a VTST VOB is illegal. This is why the original VOBs must be replaced by a blank one (approx 10KB).
However, it is possible to remove toatlly a menu VOB (VMGM or VTSM). The tables that refer to the VOBs must be totally cleared (deleted), and all PGCs that refer to the VOB must be converted to dummies. This is what PgcEdit does if you blank out a menu VOB with the option "Completely remove the menu VOB file". Obviously, this option is not present in the dialog when you blank out a title's VOB.

Soz i took solong too come back but have bean bizzy...

i need a good guide on pgcedit i blanked out the vobs as i thought 2cool instructed but then i had an invalid dvd structure or something... also need to find guide to menu edit.

@r0lZ
However, it is possible to remove toatlly a menu VOB (VMGM or VTSM). Yeah, just to clarify...
I've seen DVDs with the related tables deleted, but with a zero bytes menu VOB. In this situation IFOedit sector adjustment fills with a non zero value the start sector of Menu Vob (0xC0), and that's OK. But Nero doesn't like these DVDs, seems because it's zero bytes VOBs.

The solution I'm applying is to delete the zero bytes VOBs and adjust sectors in IFOEdit (now it fills 0xC0 with zero, because no menu file is available). In this way, Nero accepts the DVD.

My question is: Are these DVDs (zero bytes menus) really out of the standard or is Nero applying a non standard rule?

@Berrick
For selectively blanking PGCs (not sure if it is your case), may be you can give VobBlanker a try...

jsoto.

[r0lZ]

@jsoto
I really don't know what is the standard. I've read (don't remember where) that a VOB is needed everytime, but I think the author was thinking about Title's VOBs.
Anyway, there are tons of DVDs without menu VOB, and that is not a problem.
On the other hand, zero bytes VOBs are well known to cause problems with various softwares (Nero, DVDShrink...)
IMHO, it is best to totally remove the VOB, or leave a VOB with at least one small cell (the well known 10KB VOB), even if the cell is not used in the IFO.

[jsoto]

Thanks for the clarification.

I just remembered that I did that one time with a Scooby Doo cartoon DVD and it didn't work.It doesn't work to simply add the VOB and Get VTS Sectors. You have to merge or fix the VTSM_C_ADT and VTSM_VOBU_ADMAP tables as well.
When I said "...even if the cell is not used in the IFO." I mean the cell is never referenced by a PGC (ie never played). The cell appear as unreferenced material in DVDShrink. Obviously, if you leave a VOB, the VOB address tables must exist in the IFOs, and must be correctly initialized.
