Cannot Extract Subtitles from .VOB files

[ToiletDuck]

There are: DVD .sup Subtitles and Blu-ray HD .sup Subtitles.
Those are different formats!
The first one is used for DVD authoring software and is totally different from the PGS subtitles on Blu-rays.
No, BDSup2Sub does not support these. (I read the source code.)

Cu Selur

For DVD authoring soft like... pgcEdit to name one ?
Or do you actually meant BDedit?

Anyway, so is that used for audio, title / sub menus, changing / skipping scenes, previews and ton of other things you can do in that utill ..

Not sure what you mean by that  ?
