This is probably due to my limited understanding of writing Xv apps but how do you keep the app from drawing the colorkey itself? isn't it just an X rectangle? is there an Xv function that the app uses or does it just draw a rectangle and paint it the colorkey color? How does the sis driver do it (if it does)? what does the output look like with no colorkey drawn? if it just the desktop or it it just some undefined area? does Xv even work without a colokey? I thought that's how the overly worked it overlays the video data based on regions painted with the colorkey. I suppose in global alpha mode though (on radeon), it will blend the video with whatever the graphics layer shows so if I could get rid of that rectangle of color, I'd get a nice blend with the desktop and any windows over or under it.
