I have a Sony HDR-SR11 HD video camera. I would like to be able to use it as a webcam for an upcoming project because I would like to both stream live, and record what I am doing. (music concert) The service I will be using ( says I will require a video input device to make the camera link up via Firewire (Camera only does USB) and Adobe Flash Media Encoder Live.

Any recommendations on an inexpensive device (yes, I am a musician) or another good alternative?
