Jim,

I just tried a test using AG3.0.2 and the same XP + Ubuntu OS  
combination. Instead of 4 separate capture cards, I used a single 4  
input capture card (4x bt878 chips). It seemed to work fine changing  
between a number of different venues at different servers.

My guess is that the version of vic has become out of sync with your  
Video*Services. Could you try the following?
   - on the display machine, remove all the video producer services  
from your configuration, save it & exit VenueClient.
   - on the capture machine, make sure you have the latest vic and AG  
toolkit (after updating Synaptic or apt-get).
   - shut down the AGServiceManager. Now erase the Video*Services  
currently being used; something like:
         rm -rf ~/.AccessGrid3/local_services/Video*
     will do that (assuming you're logged in as the user who normally  
runs AGServiceManager). New services will be added there when they're  
needed.
   - restart AGServiceManager.
   - back on the display machine, starte the VenueClient, add the  
VideoProducerServices again etc.
