Hi Guys, I've searched and can't find my issue anywhere else. Apple TV 3 wont accept streaming from the Mac mini sat right next it or the iMac which is upstairs in the office. It wouldn't work with Lion and still doesnt work with Mountain Lion. It will load up my itunes library very slowly and when I click play its just stuck on the loading screen.. If I leave it long enough It says it will be available to play in 2-4hours! I've never waiting that long though to find out. Any idea's? I'm using the 1st Gen time capsule as the router. which is connecting via a DHCP. and on 802.11n It's been like it from day 1 but rentals and netflix work ok.
