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?
