Hi,

At the moment Wine doesn't support Video Overlay in DirectX. In order to make
DirectDraw feature complete we need this ability. It is used in media players
(in a lot of cases through quartz 'DirectShow') to improve rendering
performance. A free application that attempts to use it in directx mode (the
default option) is VLC. Further Picasa seems to need it too and their special
Wine branch supports video overlay using Xv but in a hacky way.

It is relatively easy to add a software implementation to DirectDraw/WineD3D
but it would be slow. For best performance and less reinventing the wheel we
need to implement overlay using Xv. The most tricky part would be on how to
access Xv from within wined3d.
