[Live-devel] Merging images...

The problem appears to be caused by the fact that you are receiving 
the two application's streams on different IP multicast addresses, 
but use the *same* UDP port numbers - 50000 for video; 50002 for 
audio - for each.

This is supposed to be OK; however, some operating systems 
erroneously do not distinguish between different streams received on 
different IP multicast addresses, but using the same UDP port 
number.  (What OS are you using?)

To fix this, either (i) upgrade your OS, or (ii) use different UDP 
ports in each instance of the application.
