More menu stuff done. Switching audio tracks from a menu on a DVD is a tricky bitch: you have to have access to the virtual machine status registers to read the existing state before you highlight the appropriate track on the menu, and link to the selected button to a bit of code that sets a different register (VM registers are separate read and write registers). And you have to specify the operation if it's inside the movie (like if someone hts the menu button, selects a different audio track, do you resume the movie, go to a different menu, or something else?).
Bitch is I can't do some of the linking before I actually get the files. I have links ready to go, but things like chapter marking, scene selection, and audio track selection I have to do based specifically on those files.
Grunt. I sleep now.
