Problem on My Book Live Duo as a media server

Hi everyone I,
I am new to the forum, and I want to expose you my problem:
I have a My Book Live Duo, My Book World and connected to my network with a PC with Windows 8.1 and a TV Samsung UE 46F6320; do not get to set the My Book Live Duo, as a media server, to see my files from TV, however the My Book World if it appears. I have the latest version of firmware installed (MyBookLiveDuo 02.43.03-022: Core F / W), and enabled the DLNA server, I’ve tried anyway, I was coming to show the media server a few times, but it disappears as magic …
At last someone has something?

thank you very much

Lots of users seem to have problems with the WD DLNA server which is shipped with the MBLD. The only solution is probably to install another UPnP server, e.g., the Twonky server. There are a number of threads here and elsewhere explaining how to do that. Other WD units are shipped with the Twonky server, maybe the MyBook World is one of them.

Thanks!
