VOB file of 3 GB

[deklerkt]

In an attempt to add a home-made subtitle to a DVD movie, I ripped it to disk. Using some guidelines in this forum I used VOBEdit and IfoEdit to remaster the DVD including this subtitle.
However, IfoEdit creates VOB files of 1 GB in size. The original DVD however has the main title in a single 3 GB sized VOB. I never saw this before (always sets of 1 GB).
Is there any way to instruct IfoEdit to make a single VOB file or is it safe to concatinate the VTS_01_n.VOB files into a single VTS_01_1.VOB file?

VOB are always at the most 1 gig

How did you determine the VOB from the original was 3GB? Was it on the DVD that way, or did you notice it after it was ripped?

Some ripping software will allow you to create one giant VOB after the rip, this might be what you are saying.

I have also never seen a DVD with VOB files bigger than 1GB.

BUT, there is no adverse consequence from having a 3GB VOB as long as the OS on your PC is compatible.

If authored correctly it will play as 3GB or as 3 * 1GB files with no problem on your PC. I guess you could try it out on the DVD player to find out if it's OK there.
I've never seen documentation saying it is against the DVD specs to have files bigger than 1GB (which does not mean there isn't any).

But why do you feel the need to concatenate the files made by IFOEdit?
Just leave them as they are and play-test your film on the PC.
If it works burn it. Play it on your player. If it works that's it.

I'm sorry - mistake all mine. In a previous project I needed some small VOBs to be combined to a bigger one and set the DVDDecrypter FILE setting to No Filesplitting. Hence the 3 GB. Reset it to "File" and the ordinary 3 x 1 GB come out. I should have checked the original disk immediately rather than falsely assuming that DVD disk = HD file set.
