Hi Michael,
Good suggestions, thank you.
We have a hi-end network with Why Reboot (Highly recommended BTW) and we have done testing concerning network performance. Things look pretty great in terms of speed/performance, etc. which of course makes this more confusing...
The Video streaming (AVpro MXnet) is on a dedicated switch ISO'd from the main network. We do have Domotz in there, but there's no indication of any network flooding or latency...:(
