   DirectShow question
  Hello all!  I am trying to make a program that reads in a video, makes a texture out of the frame, then plays it on whatever mesh I happen to map the texture onto.  I have the video to texture part up and running, copying a bitmap to the texture each frame, but now I have no more audio.  I believe this is because of my filters.I add a source filter before anything else, sending in my video filename.Then I add a SampleGrabber which is connected to a Null RendererSampleGrabber -> Null RendererI think the reason the audio isn't playing is because of the Null Renderer, and I was wondering if anyone could help me out in how I can possibly get around this.  Should there be another filter somewhere?Thanks in advance for the help!   
  Google VMR9   ;  Got it.  Turns out I needed an "AVI Splitter" filter to divide the output into two pins, video and audio.  After that I connected the source filter to the avi splitter, the video output to my sample grabber, and the audio output to a directsound filter.
