Background - Video in DVD Menu


I’m using the NeroVisionAPI to create DVD-Images with menus. If I use the NeroVision default templates (Island etc) to create the menu everything works fine. Also if I create my own templates with image- or just colored menu-background everything is fine.
But it doesn’t seam to work to create a menu with a video as background: when I call EstimateCreateNeroBurnContextTime the program crashs with memory violation. The crash occures within EstimateCreateNeroBurnContextTime. Before crashing ‘EstimateCreateNeroBurnContextTime’ calls a few times my callback functions and that’s it.

Has anyone ever created a dvd with video-background in menu or any similar experiences with EstimateCreateNeroBurnContextTime.

Thank you!
