I would look at DVdriver, and see if that helps. It should allow you to take any video input and have the OS see it as a 'webcam'. Then you can stick with your existing hardware, so long as it has the ability to connect to the computer. Since you already have the camera, all you would need to have is a video input (video card) that accepts the native video out from that camera.

As to Talking Stick, or other similar apps, it leverages an external media server and displays the stream(s) in the pod in Connect. So it removes some of the barriers of getting the video in the room by removing Connect's limitations, but it also demands more bandwidth and if your session is recorded, then the video from the external media server will not be part of the recording.

Hi There,
I have just spent a frustrating day trying to make a number of different video cameras work as external video sources to Adobe Connect. I've tried it on both Mac and PC's. It seems unbelievably difficult to make work for something you would think many users would want to do. I called the Adobe support line and all they could offer as advice was that if I had a digital video camera with a USB port and a driver, it should just work. I wonder if anyone can offer me a simple solution and list the hardware and software that I need to buy to make this happen. I prefer a Mac solution but at this point would live with a PC solution if necessary. Thanks in advance.

The easiest thing to do is to get a camcorder that supports a PC/Mac interface directly.  If it does not, you can use a capture card or a device like this:
