Is this anything to do with C++ or MFC? If so please clarify what you are trying to do and what errors you receive.

I must get a clever new signature for 2011.

You can use IMediaSeeking::SetRate Method. Obtain the IMediaSeeking interface from FilterGraphManager. I had tried this once, but the required filter in my graph(probably source filter or parser filter needs to implement this method) didn't implement this method. As it was for video playback, handled the play back rate manually with GetPositions and SetPositions methods of IMediaSeeking. However i think this is the only interface that the FilterGraphManager exposes for fast forward and backward playbacks.
