title: Recording composite video to an audio file
body: <p>I'm trying to record raw composite video siganl to an audio file by connecting the yellow rca cable from a player to the mic input in my pc so I can then put the cable in my audio output and connect it with the video input in an old crt tv and play back the signal to the tv so that I can view the original video.
  But that didn't work and I can only see random white lines.
  Is that due to frequency limits in the audio format or in the onboard audio chip, or is analog-digital conversion and the other way when recording and playing back damaging the signal?</p>
