Is it possible to convert a video file to an audio one? Or else to separate the audio track in a video file for use as an MP3 or CD track? It seems to me there should be a way to do this, but I haven't been able to figure it out. DISCLAIMER: not asking for the purpose of illicit profit. I just have come across a number of items that I can only get on DVD and would like to be able to listen to them on CD or MP3. Any suggestions appreciated.
