Most camcorders don't automatically act as webcams, which is what you are attempting to do...use it as a webcam. Often, you have to download drivers (at least on Windows) that will allow the operating system to use the camcorder as a webcam. You might google "using muvi camcorder as a webcam on Mac" or something similar to verify that it's possible and that you have the drivers needed, etc. Once you are able to use it as a webcam, you should be able to add it as a source in icamsource. Hope this helps!
