I encountered the same issue and found the problem to be the disc’s Main Timeline property – it was set to the chapter/scene that would play when I pushed the play button on my player (after I get bumped from the DVD’s main menu to the player’s screen by pushing the stop button). To remedy the problem, I simply changed the disc’s Main Timeline property to be the timeline I intended. To do this using Encore DVD 2.0, click on the disc icon (furthest left icon) in the Flowchart view, and adjust the Main Timeline property in the Property tab.
