I would like to make my Xvideo appear translunent by using alpha blending of my video image against the "desktop background". However, each time before the before any of the Xv PutImage() is invoked, after the window is created, it appears that the background of the window has already been painted to some color, like black. I would like to prevent such things from happening.
