I have a WD EX2100 and got a Samsung TV UN55JS8500. Surprisingly, when pressing Source, the TV actually let me select the NAS and was able to play videos stored in the NAS.
(the TV will show my PC as well, although for some reason it shows 0 videos on that PC... but that PC definitely has some videos on it)
What technology is this -- is it DLNA or UPnP? I think the video appeared less smooth than if I play the videos on an iMac, or if I pass the video output to the TV using HDMI. I wonder if the video is transcoded when played, and what types of video formats (mp4, avi) are supported?
I wonder if using a computer may still be a better choice, as it is more customizable for audio or subtitle selection, and I can also make some DVDs into a single .iso file, and play it on the computer using VLC player, and have no need to swap the discs in or out, or worry about having the disc scratched or misplaced.
