2 way A/V chat : camera selection and settings

Hi Folks…

I was running some sample code for a 2 way chat app. It was recomended that 2 cameras be used, well there is a built in camera in my laptop so I fixed up an external webcam as the 2nd cam. I have alreay published the two fla files as webpages. When I invoke both these html files, the video feed is only from the built in camera. How do I tell the system to use the external webcam for one of the html files? I am using FMS 3.5 and the code sample is in AS3. I Hope someone can advise. Thanks.
