  19  *
  20  * Status:
  21  *      - plays .avi streams, video only
  22  *      - requires Microsoft avifil32.dll and builtin msvfw32.dll.
  23  *
  24  * Todo:
  25  *      - audio support (including synchronization etc)
  26  *      - replace DirectDraw by a 'normal' window, including dithering, controls
  27  *        etc.
  28  *
  29  * Bugs:
  30  *      - no time scheduling, video plays too fast using DirectDraw/XF86DGA
  31  *      - requires DirectDraw with all disadvantages.
