I have seen a lot of discussion on this topic. For some people, everything is fine, for others not. Here was the problem… when accessing network shares on a Windows 7 machine, I would get the error “there is no media in the current folder” or “the network share can not be accessed”. I followed the advice of others with no luck…
For example this is a very good tutorial: http://www.youtube.com/watch?v=EQstgQ4eJCM

SOLUTION: For me the problem turned out to be that I was also sharing a printer on that machine. Out of trial and error , I removed that printer share and suddenly everything worked. I added back the printer share, and it broke again, so this was definitely the problem for me. I suspect the WD TV sees the printer first and chokes on it. Hopefully this post will help some of you who are stuck like I was.
