WD TV Live won't find MyBookLiveDuo as a media server

I have a 6GB MyBookLive Duo NAS with media server enabled.  I recently purchased and setup a WD TV Live media player.  The player works fine and recognizes network shares from the NAS, but it doesn’t recognize the NAS as a media server (doesn’t appear in the list of available media servers on my network).  Any ideas?

Does anything else on your network see the media server.

Yes - my Windows 8 laptop does.

Also – the WD TV Live box recognizes two Sonos media servers on the network, but not the MyBookLiveDuo.

any update on this? exact same situation over here.
