Play the ah film.
If you just want the sound, run a sound program and record it. Make sure your recording device isn't the mic, but "what U hear" assuming you have a creative card. Also, creative has a sound editing program that comes with the card called Wave Studio.
How I did it was I opened the film and let it load, then I opened my Wave Studio and hit the record button, then I switched back to the AHFV and hit play.
When you are done, just switch back to Wave Studio and hit stop.
