Why are you “editing Metadata” ? the WDTV has a Get Content Info Scraper built in, that will do it Automatically .
Firstly, you need to add your Network Shares (from the MyCloud) to My Media Library * (and make sure your Media Library in “On”)
* see here: http://community.wd.com/t5/WD-TV-Media-Player/Sort-Filter-doesnt-work/m-p/860515#M2310
Once you’ve done that … press the Content Source Button that’s the “A” button in RED on your Remote Control … and select " My Media Library"
Secondly, if you have your Movies in “Individual Folders” then Metadata eg. Plot, Actors, Genre will Not Display (you’ll get get N/A)
also, the HOURS you’ve spent … have you looked at the User Manual ? (most of what i’ve said is in there)
