so i lost my internet connection tonight, not a big deal i though, i have plenty of my own content on my mac mini, so lets just watch it on my ATVs. i tested it on 2 of my ATV3s, and none could play a file through the "computers" app. i restarted each atv, my itunes, and my airport express and could never get it to stop spinning the loading logo. i could browse through my selection, but once clicking on something, no go. i CAN watch content by going down to my computer, airplaying directly through itunes, and then picking something to watch. what gives?
