I think your got your wires crossed JStalin, you simply cant put 2 original menus of 2 different DVD's onto the one DVD expecting to run 2 separate movies. How do youlink one menu to the other to allow you to selct the second movie? It can all be done manually if you author each movie and menus to the one DVD but you cant simply use the files you mention to add extra buttons to a menu to link to another menu.
