   DirectShow - blicking
  Now i write simple program which plays sequence of the video clips through DirectShow API.And i can''t find a way to prevent switching from fullscreen to windowed mode at the end of each clip and back to fullscreen mode at the begin of the other clip with a terrible screen blicking.IAMMultiMediaStream + DirectDraw somehow solves this problem, but this interfaces doesn''t allow to scale output media (as i understand).
