I have MC 18 and have an issue with the DLNA server being slow to detect when I first turn the TV on. Sometimes it can take upwards of 5 minutes to detect. For this reason I have been using Mezzmo for my DLNA server as it is always detected immediately for some reason.
Anyway, I asked about the problem a while back and I think it was determined the issue may be related to my Virtual Box virtual network interface. I'm just curious if this issue still exists, or if there is any way to "bind" JRiver to just the one network interface so it will be detected more quickly.
EDIT:
Thought I would add some extra info here...
The Media Network log has a bunch of these messages in it under Device Discovery server:
M-SEARCH:
http://239.255.255.250:1900*
and
NOTIFY:
http://239.255.255.250:1900*
When I list out my interfaces I can tell both are on the 192.168.0.0 network, so I'm not sure what MC is doing searching the above addresses.
