OK I have something strange going on.  I have one node multicasting video and 
another running unicast.  If I connect to the Argonne Lobby venue with my 
multicast node and bridge my unicast node through NCSA I can see my multicast 
streams on my unicast node.  If I go to another venue or enter rooms on the 
Argonne venue I don't receive my multicast streams on my unicast node .  I also 
haven't found anyone outside of the state that can see my multicast video even 
in Argonne's Lobby.

Any ideas what might be going on?  Also how could I receive my multicast 
streams on my unicast node unless my multcast streams are getting to the 
Argonne Lobby venue and once there why can't others see it?  We are 
troubleshooting multicast problems here and I was using our unicast node to 
tell me when we were able to send multicast streams out.  I'm puzzled by this.  
BTW I am able to receive multicast streams from the venues/rooms.  Our problem 
seems to be sending multicast streams out.

I have attached a snapshot of my multicast and unicast nodes.  The image on the 
left is the multicast node and the one on the right is the unicast node.  The 
images at the bottom show that I am sending/receiving video from my nodes.
