It seems as though the problem is the incoming data needs to be forwarded to the computer which wants to receive the video, the problem though is that AOL video appears to use a very broad range of port numbers for it's incoming video, everything from 1024-5000 which is a lot of configure for forwarding.
You can do this by looking up port forwarding for your particular model of router and directing them to your computer's IP address but the easiest way would be to use routed IP and set up your computer with a public IP address so the computer is directly accessible from the internet, rather than just your router but this has disadvantages with security and you need to have a block of IP's available to use which you would've needed to request at time of order.
I would recommend against using AIM for video and use something like skype which only uses a single incoming port for video which can easily be configured using guides available here: http://www.portforward.com/cports.htm this site also includes guides for forwarding the thousands of ports AOL video needs if you really want but I couldn't advise it.
