I have a Mac Book Pro and it has Mountain Lion 10.8 installed in it. I also have an Apple TV 2 at my home which has AirPlay in it. I wanted to stream videos from my Mac Book Pro to Apple TV 2, but I was unsure about it. I had seen my friend streaming music, but never seen a video streaming. Can someone tell me if it is possible as I have AirPort Express in my Mac Book Pro?
