I have an old camcorder that I want to use as a webcam and I was wondering how I would be able to hook it up to my mac. It's not a DV, it's the one that uses the small cassettes. It does not have any USB cable or anything...only the red/yellow/white wires to hook it to the T.V. Does anyone know how I would be able to set up my camcorder to use as a webcam? Also, if I wanted to video chat with a person that uses a PC, would it be best to use Yahoo Messenger? Thanks in advance.
