I don't know what you are trying to do, but try first searching wikipedia.org for terms like : composite, s-video, firewire etc. You will find it a great help.
Thanks, I was testing some footages I made with my A1 , the video quality looks brilliants but no sound so I thought sound is not coming out of such cables, is this true ?
Your camera should have an audio/video output. Use only the white and red to connect to your monitor/tv audio inputs. The yellow jack is video signal only again.
