Not really. I was making really cool menus long before I knew what these were. It wasn't until I started copying Studio DVDs that I started getting into the structure of VOBs and IFOs, and then that was just to remove FBI warnings and studio logos. Since he is working on a straight transfer of the film from a capture, DVD structure at this point in time, is a needless detour, though I agree it is important to learn for more ambitious projects.
And should that time come, let me know. I've got oodles of links and documentation that I can post for you.
