When I play movies from my late 2013 2.3GHZ 15" connected to my appleTV over AirPlay movies play as though the TV had a 30GHZ refresh rate or the videos are low fps. It is especially noticeable on fast moving movies. Bandwidth shouldnt be a problem as I am using a Thunderbolt to Ethernet adapter on the mac and the Apple TV is also hard wired into the router. Everything runs perfectly smooth using an i7 Win7 box with the ios AirVideo app. Anyone notice the same thing or know of a tweak to make AirPlay work better? I see the same choppiness over AirPlay with Quicktime playing mp4s and VLC playing 7gb MKVs.
