独占模式视频播放能力 directshow90版本。现在可播放视频从AVI回来，MPEG文件以及DVD标题

即使在DirectDraw的全屏独占模式。预计这将是

非常有帮助的游戏和互动内容的发展。 -General Information:

====================

Now video can be played back from AVI, MPEG files as well as DVD titles

even in DirectDraw exclusive fullscreen mode.　This is expected to be

very helpful to games and interactive content development.



The DirectX SDK includes various components that together

offer this capability.　An updated Overlay Mixer filter in DirectShow

is now capable of using a DirectDraw object and primary surface provided

by an application, rather than insisting on using its own.
