Now they make up an entire film and each VOB works but I dont have the core files like the Video_ts files etc. My question is can I import those .vob files above into a DVD authoring program and created a full DVD video structure again?
I haven't done this but you might want to use a program like Voblanker or FixVTS and maybe those programs can fix your DVD structure and make a Video_ts and BUP files! But I can't be sure.
Thanks for all the help and info guys, I may have gone the long way around but this is how I got it working:
there was a fault in the first .vob file causing it to fail when importing it into DVDlab, so I used FixVTS to repair that VOB and then I could import it into DVDlab, and demultiplex them all, and finally recreating a DVD structure.
