I just loaded the newest version of plex on a brand new Mac Mini. My plan is to run multiple Apple TV's on a local network that communicate with the Mac Mini as my Plex Server. So I have four digital copies of movies downloaded to my iTunes account. I direct the Plex Library page to the appropriate pathing to where the movies are stored on the Mac Mini Media Server. Once I click save changes, all of my movies load with all of their posters and everything. It all looks like it should work but once I click on any one of those movies, they give me the message of "There was a problem playing this item." I also get the same message once I connect an Apple TV, everything loads right with posters and correct movie names, but the same message occurs once I try to play the movie.
Any help on this issue will be greatly appreciated. Thank You!
