we are blu-ray applications developers and we have a problem with repainting graphics layer over video layer. In MHP this problem is solved using the method call repaint() to the HScene. This Method remove all graphics and paint again. But in Blu-ray is not work correctly. When you have a graphics over video, this graphics don´t disappear when you paint other graphics, because don´t refresh the HScene and all the containers get painted over the others.
