Hi Jstineh,
Sounds like we're doing a similar thing.
I found that I could import the vob file, make the edits and if I set all the bit rates to max for the save the quality is practically identical to the original. The file size is bigger though.
My problem is now that when I rename the mpg to vob and insert it back in the file structure the new dvd plays OK until it gets to the section relating to the new vob and then will not play this bit...
Is this because I have changed the length of this vob section and it does not now align with the info in the other files?
Thanks Jules
