I use to have WD Live devices on each of my TV's pulling from a network share. The problem is once you get a super large library (over 1000 movies, hundreds of tv show episodes) the WD Live units bog down and are slow to scan (5 minutes initially on power up to over 15 for a large library) and you have to wait to use them.
The WD Lives cant be left on or plugged in, each of t he 3 unit I had would get extremely hot, even left plugged in and powered down. We took to unplugging the power from them when we wouldn't be home for a few days just to be safe.
I ended up going from WD Live to Plex and have been much happier with it. I have the Plex media server installed on my PC and then placed Roku 3
s at each of my TV's. We can access the media anywhere in the house now, including our tablets. With plex I can even access my media files at home while traveling using my tablets as long as I have a good Wi-Fi signal.
Plex also automatically locks into my ITunes library seamlessly and allows me to pull up any music or playlists through Plex.
One of my TV's does support DNLA, and so does my R6300 router. I initially tried to use that to serve up my media but it didn't send Metadata. And while the TV will see the DNLA media files from any server, it will not play mkv files. Hence my using Roku 3's everywhere.
With Plex android tablet you can throw any media to any player in the house you want. On the Ipad you can download/sync any media... I do wish both devices supported both features instead of one and one.
