You can play a video in a moveable window that 'floats' on top of everything else with Picture in Picture, so you can view it no matter what you're doing. You can watch web videos on any HDTV with Apple TV using AirPlay, without having to show everything else on your PC.
- Navigate to the web video you wish to watch in the Safari software on your Mac.
- In the video controls at the bottom of the video window, there is an AirPlay symbol for compatible web videos.
- Select your Apple TV by clicking the AirPlay icon.
