Streaming from a Camcorder

You are talking about a direct signal to your PC? I agree with R Proffit, most modern camcorders will not pass a signal through. I have done it with a Canon HV20 which is a tape based camcorder and uses FireWire to connect to my PC or HDMI to record to a DVD recorder.
Your best bet is to get a decent webcam, some of the Microsoft units may be the answer. I don't expect you can fiddle with the camcorder software and get a successful result. OR Set up a DVD recorder and feed it from your camcorder.

In short. Start again and do your research before buying.
