I'm trying to "create IFOs" for a group of VOB files, and I get an error, "Could not find any VOB unit in VOB file(s)." I don't understand the problem, and could use some help, at least understanding the error message, if not fixing the ultimate problem. THANKS.

The VOBs in the group are of 2 different kinds:
(A) generated w DVD-Shrink, by trimming down to individual short clips, with each clip generated as its own little movie. Each movie-let played fine. I then took the VOB files out of their indiv. folders, put them all in one main folder, and tried to create new IFOs.
(B) generated in a similar way, using .mp2 clips captured from VHS in ULEAD Video Studio as a source, and using that tool to generate a DVD-Video fileset, as in (A), with the VOBs moved to the same main folder.

(BTW, I tried joining all the VOBs with VOBedit, and generating IFOs. That worked, except that (A) files have AC3 audio, and (B) files have PCM-Audio, whatever that means (seen in VOBedit), and the audio in those clips gets lost.)

Yes, I got that once before too. You need to rename the vob files to VTS_01_1.vob and up for it to work. That should fix it, good luck.

Hi all
I'm having exactly the same problem as mikewillnot did.
I renamed all VOBs secuentially but still canīt play the whole new movie.
Actually, only the first chapter gets played.
By checking the file structure with IfOedit it shows I have only one chapter associated to cell 1. Somehow the others VOBs (5 of them) are not recognized at all. Does it mean the those 5 VOBs don't have IDs??
Any help is most welcome!!! regards, josesol

This is what I do here, seems to have worked thus far for both episodes and movies.

The one time I got what you got, was when I didn't have the vobs numbered correctly. If you mess up after 3, it only does the movie to vob 3. You need to rename them all VTS_01_001.vob, VTS_01_002.vob, . . .VTS_01_009.vob, VTS_01_010.vob. I don't know if that was the problem or not, hope it helps. I used that method by joshua for the complete Goofy cartoon series, took 4 discs with about 13 episodes a disc. But also works with movies as I joined one movie and a short video after it too. Just follow his directions.

Hi Josh,
thanks for replaying.
I'll check closely on that thread tomorrow.
BTW, tonight I tried with only two chapters from different DVDs, and no matter which one is assigned VTS_01_1.VOB, it is always the first one which gets played back. Somehow the VTS_01_2.VOB is not recognized, as it never existed!!!!
Cheching again with IFOedit, it shoes there is only one chapter/cell in the set.
I bet I'm missing or doing something wrong again and again!!!!
When I make a set with chapters from the same DVD, everything goes smooth. Go figure!! Heeeeeelp Please !!!
