The black DIN plug is S-video in to the converter device. Your camcorder probably doesn’t support that. All you need is the yellow composite video cable and one of the two audio channels. The old video camcorders typically only have mono audio so the red or white will work for the audio transfer. You just have to make sure your software is recording on the appropriate channel that you connected to on your converter device. The resolution will be pretty terrible but hey it isn’t high def is it?
