Don't quote me on it, but I think the pink bar is the area of the video
overlay buffer that can't be used or doesn't exist. That is, the issue
isn't scaling, but the video plane itself. It may be that the 9000
simply doesn't have a big enough video overlay. Try setting the video
mode to 640x480 or 800x600 or something and playing the 1080i video. I
think you'll still see the pink bar, scaled down to fit the screen.
