Todd,

Newer versions of AGTk have updated input detection/selection code to  
accommodate V4l2 devices available in new UCL vic. This means that  
the ordering of detected devices is different to previous versions.  
Its likely that your VideoProducerService's were configured with the  
older device ordering, leading to problems similar to those you're  
experiencing.

I recommend that you Remove the existing services (don't just try to  
Configure the existing services), then Add new services (and Store  
the result).
