aleluja;CDuncle seem to be pretty knowlegable on this so his advice is better than mine.
The error DVDStyler shows:
ERR:SCR moves backwards,remultiplex imput.
Is telling you the vob has a time code problem.
This was done by one of the other software you used on the vob.
If i understand this the vob plays to that point then hits an earlier time code(timestamp) that tells it to go back to a place it has already played.
