I managed to build a very simple 1-screen menu gathering all the small features like language selection, and I also made good use of the auto-chapter feature of DVD Lab Pro 2.
After the burn + thorough testing on my stand-alone player, it has no bug and the audio is now fixed...
My next project will involve a dual-layered NTSC DVD on which I intend to add a language that wasn't featured on the original release.
I wonder how hard it is to rip the original menu structure, add the language, and reconstruct it anew ?
Any tips for the newbie, ADM ?
