Seems to me that there may be some problem with identifying correct video signal or so on. Only the things that helps is disconnect affected input signal and reconnect it. Changing routing or trying to route signal to the other output does not help. And you can even see video input image on the Smart Videohub monitoring display, but signal is not going to any output.
In other words, you change something on one device, that have outputs hooked to the router, and router will block some other video input.
We noticed on Smart Videohub 40x40, connected together with Newtek Tricaster 8000 and few cameras, that time to time starting or ending session on the Tricaster may hang some other switcher inputs, like directly connected cameras.
