To confirm, the WeTek Core can run all my media from my WD MyBook Live NAS right?
Up until a few months ago I had a WD Live (worked perfectly to access my NAS over Wifi and play any/all media formats/types) - then my son smashed it on the ground and now they don;t see WD that also has Netflix (which I also use) - was looking for a replacement and the Wetek Core looked awesome - but can it really stream media from my NAS? If so how? is it native?

Looking for details on the PROCESS, needs to be easy enough for my wife and kids to browse and load ... like the WD was ...

Its just the Standard setup as for all Kodi devices...connect the Core to your home WiFi Network and then you add your Networked Shares from within Kodi:

To make it easier most of us just add Networked Shares using Zeroconf Browser, using point and click.
Add your Shares once and then thats it, no need to do it every time unless you want to add extra folders from your NAS.
