Hoping someone can help, I was given an ATV3, and just not sure how to set it up to read my media files from my NAS drive which contains mp4/mp3 files. If I drag the mp4 files into iTunes on my MBP I can view them on the ATV, the problem is that this way they are stored on the macbook... (not good on a 256gb ssd) So basically I need info on how to either get the ATV3 to read directly from the WD MyBookLive (has Twonky server running which my PS3 reads from fine) or how to configure iTunes to not store the video files locally and always read from the NAS. Any help will be appreciated, i've been searching all morning but looks like it's not possible... which i can´t believe... Ideally i would want the ATV3 to read from the NAS drive directly, but I believe that would require a jailbreak, so I would be content with sharing via iTunes but without having to copy the files to my macbook. Note: the WD MyBookLive NAS drive has an iTunes server also, would that allow the ATV to read directly from it?
