Video starts automatically when I turn on WDTV? (feature or bug?)

Whenever I turn on my WDTV, it starts playing one of the video’s in my collection. It is always the same video, which it starts from the beginning.  It appears to be the first video in the list (alphabetically).  I’m connected via media server to my NAS.

Anyone else experience this?  Is there an option to turn this off?  

A quick way to overcome this would be to reset the player to factory defaults.

It almost sounds like “Auto Play” … but that’s only supposed to do it from usb ? oh well, worth a try 1st (before resetting your device)
