I too have the same problem with accessing my media over the network. It started since I did a firmware update to 1.03.49 official release, yesterday night. Until then it worked fine!! I tried rolling back to previous f/w (1.02.21)… to no avail.
My network settings are:
Network discovery: on
File/Printer sharing: on
Public folder sharing: off
Media streaming: off
128-bit encryption: on
Password protected sharing: off
HomeGroup connections: use user accounts…
Also, on my WDTV Live I have cleared network shares login info and switch off and on again the auto login option.
Still, when I press the OK or Right-Arrow button trying to access either Media Center or Network Shares I get no response whatsoever.
Anyway… any ideas would be appreciated…

PS. I hope this is the right thread…
