I still don't get what Plex exactly is. All I want to do is streaming my .mkv / .iso files from my NAS to the AppleTV (like I do it right now with a cheap WD TV Media Player.
I understand that it is not possible with Apple TV (without an App). So is this what Plex is all about?
Thanks
Plex will require a computer running, it will take stuff from your NAS transcode it to the format you require and stream it to your device, what ever it may be.
I just recently set up my server with a 2012 Mac Mini, and I am truly surprised how well everything just works. Stoked for the release of their app.
