According to the 'Publisher's Description':
This software tool is an important component that allows you to easily access and interface with the My Book World Edition, WD ShareSpace and My Book Live network attached storage products along with the WD TV Live products. WD Link provides quick access to the web user interface to configure drives.
Just wondering: (1) if it is already installed on my WD TV Live Streaming Media Player (there's no mention of it in the User Manual) and (2) if there's any point in installing it on my computer (which is on the same wireless network as the Player) and if so, what for?
