I found a similar post from a year ago that was never resolved. My WD TV Live works great after I finally discovered that Windows 7 requires the folder to be shared by Everyone (as opposed to Owner or Homegroup). However, Windows 7 loses the share every time I reboot. I have to assign Everyone again to the folder I want found by WD TV Live.
Why? Thanks for your reply.
Windows 7 32 bit using WD TV Live with a wireless connection (Netgear WNDR 2000).
