How can encore continue playin the same background music when the user is switching between main menu and submenus? and not having to restart the song when you choose a submenu.
There is plenty about Encore to be frustrated about, but you should spend a bit of time investigating Scenarist or DVD Lab Pro (authoring programs that provide scripting). They are also missing some "features" (that are related to limitations of the DVD spec). And their price tags indicate why Adobe licensed the sonic authorcore only, and not "Scenarist" itself for the Adobe authoring component.
