I have the same problem.
I have a Sony Bravia which I don't expect to see the DLNA server, but doesn't...
and I have an xbox which doesn't see it either.
DLNA server is turned on, I have my public share with "Media Serving" set to "ALL", I have
one user, and under "Settings>Media>DLNA Media Server" I am able to select "Generic Media Server". The IP of this device (10.0.0.11) is NOT the same as my xbox, in fact when viewing "attached devices" on my Netgear N600 Router, there are no devices with that IP on the network anywhere.
I don't care if my Bravia sees the DLNA server at all, but it frustrates me that my Xbox sees my two computers on my network, it sees my attached USB external @ my router as a DLNA server, but it does not see my MBLD.
p.s. I have turned off my DLNA server on my router and the problem persists.
