My WD Live has been working fine for nearly 2 years! It was connected to my old non-HD TV via composite and worked flawlessly.
Recently I moved it to my new HD TV connected via HDMI. I also upgraded the firmware several versions (to the latest) and have since been having repeated issues accessing the media from my XP fileserver.
Media plays fine most of the time, and then randomly I get the blue spinning circle trying to access the media listing on the shared folder. Sometimes after about 2 minutes it recovers, sometimes not.
A reboot always fixes the issue. This is happening every 1 to 2 days.
