It is, oh but it is........it's like iPads, for some it's just a breeze, for others, they run into a few problems. Just stick with us and you'll be fine!
Hey man I recently bought an Apple TV and was having the same problem my ipad wasnt streaming the videos to the TV but I could hear sound. You have to update the Apple TV and the Ipad to the latest versions and then it will work perfectly.
Double tap the home button and go all the way to the left and the airplay button should pop up after you have it all updated.
