I finally got it working "right" (?) at the full screen overlay mode by specifying "fullscreen = 640x480" and adding "640x480" mode for XFree86 config file. However, I have impression that this image is interlacted and that only every other frame is being displayed. or so it seems to me, am I wrong here?
