--- Comment #17 from Stefan Dösinger stefandoesinger@gmx.at --- Ddraw overlays are essentially nonexistent. Do you have an application that needs them? I am generally interested to implement them, but so far I have only one application that is not a video player that makes use of them.
Note that YUV->RGB blits are supported, that's enough to make many video players happy.
