I can not add another audio or video track to my menus in DVD Architect. There is already one of each, but when I click the button to add one, the option to add new tracks is greyed out. If I try and use a shortcut it will not let me and plays the error noise.
Those buttons are for creating alternate (ie, language and commentary) tracks and alternate angle tracks in your movies. DVD menus cannot contain either of these. This is a factor of the DVD specifications and not a limitation of DVD Architect.
