// This application uses a Multimedia stream to render 
// a video file to a DirectDrawEx surface contained in  
// a window. It implements a primary DirectDraw surface  
// and an offscreen DirectDraw surface to optimize individual  
// frame blits. It also attaches a DirectDraw clipper to the  
// window to process window overlapping. 
 
 
//To compile this program you must have DXMedia SDK 5.1 installed  
//and you will need set your include path under tools/options/directories/include 
//to c:\DXMedia\include and your library path to c:\DXMedia\lib 
//Also link with the following libraries under project/settings/link...
