Help on using my Sony camera to stream - Audio/video stream recording forums

I have a Sony HDR-SR11 that i would like to use to stream. It does not have an option to do usb streaming. Is there another way to use this camera to stream? I thought maybe if i could output video to a capture card and stream that. I don't want to buy new stuff and find out it won't work. I plan on streaming live billiard events onto ustream or livestream. My camera i'm using now is a sony dcr-hc85. This camera does usb streaming, but only with windows xp. I plan on getting a robust computer to do this and would like to use windows 7 so my current camera will be useless. Thank you for any help you may provide.
