I saw a thread (In a PC forum) that said you can use a certain program (Dvd Remake pro) to put two dvds with full menus on one dvd. It puts a menu above the two menus and asks You which disk you want to go to. Can you do this on a mac?
Sure could. You'd have to reprogram the whole friggin thing with dvd studio pro though. It would take quite a while, and some skills.
