I try to make a motion menu in maestro, but fail. the menu structure like this: Three buttons: root menu: motion, duration: 12s. links to the movie. chapter menu: "motion", duration: 0.01s. links to the chapter menu. subpicture menu: "motion", duration: 0.01s. links to the subpicture menu. everything works well, but when I test my authored dvd in powerdvd, it can't get the chapter menu when I click the "chapter" button, same as subpicture button. but the movie can play when I click the "PLAY MOVIE" button, but everything works in Maestro preview. who can tell me why?? or give me a maestro guide ?? :D :D :D thanks in advance!!
