// AACSBREnhanced.h: interface for the CAACSBREnhanced class.
// 
//////////////////////////////////////////////////////////////////////
//  CAACSBREnhanced: (A DirectShow (DirectX 8.0) filter)
//
//  Purpose: This filter is a basic Transform Filter to process video
//        
//  Usage: 
//  1.  Register the filter. 
//      regsvr32 AACSBREnhanced.ax
//
//  2.  Insert the filter into the graph to process video data (live 
//      capture or video files)
//      a.  Use the GraphEdt.exe (in DirectX SDK) to build a graph 
//      b.  To use this filter in App, include iAACSBREnhanced.h for
//          definition of interfaces and build the graph in the App.
