Charles,

You are seeing normal behaviour of vic with multiple video inputs. It  
is one of the reasons why a room node is better off using a separate  
machine for the video capture. Then (out of sight) that separate  
capture machine would run 4 VideoProducerServices, while the display  
machine (where you'd be working from) can then have just a single  
VideoConsumerService (and, of course, the AudioService).

There is at least one alternative using virtual machines. However its  
a bit complicated to set up - an example at:
     http://www.vislab.uq.edu.au/research/accessgrid/software/xenag/
uses Xen on Linux to do this. If you must use Windows then perhaps  
something similar could be done with VMWare?
