Hi.
I am having issue since long time on my WD TV Live Streaming (WD TV Live 3rd Gen)
I can access network files on windows 7 pc and watch movies. However if I turn off wdtv then after next turn on I can access network files, can browese them but if I select any file (movies) all I can see is rotating arrows and movie will not start.
The solution is to reboot the wdtv and then I can access files again and play them.
The workarround would be to leave the wdtv after watching movie so it will turn off automatuically after 3 hours. So on next turn on it will work.
In the past I had WD 2nd gen and had same issue - and this was reason why I change to 3rg Gen.
I use windows 7 and apple extreme router, Wdtv is wired connected.
