Some questions if you don't mind:
How old is the unit?
In terms of networking, is it possible to manually specify the network share you intend to connect to? I ask this because I have network share discovery issues with my WDTV Live.
Could you confirm that you still have the packaging and all manuals/discs/accessories.
Considering you say perfecte staat, I assume the unit is working and also has no physical defects (scratches, etc.)?
