Tyler,

I assume you're running a single machine node - not a multimachine  
room node, just a single laptop or desktop. In this case you shouldn't  
run a separate Service Manager at all; when you start up the  
VenueClient any other necessary services will be taken care of  
automagically.

Also in this single machine mode, the default video setup of  
VideoProducer and VideoConsumer services is not ideal - that setup is  
really intended for the display machine of a multimachine node. As was  
suggested previously, a single VideoService is best for a single  
machine node. Be sure to remove the existing VideoProducer and  
VideoConsumer services first, _before_ adding the VideoService.

To summarise, the only services you should have are the AudioService  
and the VideoService. Don't forget to save the new service  
configuration (and also make it the default while doing so).
