I want to stream using 2 cameras. How do I view input from 2 cameras simultaneously?

I have two cameras installed successfully but I want to be able to view the input simultaneously then select and switch between the shot I want

Same thing here. I have two cameras, two licences for BVSS on two different computers, each one works ok independently, but I want to display both in iframes on one same webpage. As they are on the same network, and as Flash uses port 1935, I suspect there must be a collide between both streams. My visitors only see the first camera. Is there an easy way to use a different port for Flash to get the second stream through? Or is my problem due to something else?
