I want to make a rip from a DVD with the original DVD menu. But now I got some problems to sync the chapters with the new movie stream. I ripped a DVD to a lower bitrate in DVD compatible format and Authored it with one audio stream and 5 subtitles with DVDMeastro. So I got now new .vob files which contain the same chapters as the DVD. Now I want to use the original .IFO files to keep the menu. This works fine but when I want do select a certain chapter my DVD player jumps to the wrong place in the film. I guess that I need to update the sectors in the original IFO, so that the player could find the right place in the vob file e.g. if I select chapter 9. Do anyone know a method to update these sector infos? I couldn't to this manualy because there are more then 1000 lines. It would take too much time to to this.

thanks,

Nathon
