Turns out I didn't solve my problems with this DVD like I thought. Short of learning how all of this works, the best way I can think of is to find a way to backtrace what commands lead to any given menu/pgc/whatever. I know what I want to skip over, thus if I can find out what leads to what I want to skip over, I can probably get the results I want.

Anyone know what prog can do that?

Hmm, I see that PGCEdit does...but it isn't making things any easier. Cripes.
