Simple task, huh? ;) I suppose there is a guide around here somewhere...
Trust me, it is simple.........
Not sure about a guide but I am more than willing to point you in the right direction.
Once you have your US NTSC DVD files backed in on your HDD and the GOUT project DVD files you want to add the French soundtrack to also backed up on your HDD, I can talk you through it.
The software I use is PGCDemux and IFOEdit which are both very small and free.
