Hi opsuzie,

You can watch movies you have purchased and downloaded to your computer on your Apple TV if your computer model supports that feature.

Can I watch downloaded movies on TV? How?

Yes, if you have a widescreen enhanced definition or high definition TV and a network with broadband Internet access, you can use Apple TV to easily view movies from your Mac or PC's iTunes library.

AirPlay Mirroring lets you show exactly what’s on your Mac, iPhone, iPad, or iPod touch screen to everyone in the room.² Show web pages, games, photos, videos, spreadsheets, class material, and more on your HDTV via Apple TV. Zoom in and out and pause for applause. Rotate from portrait to landscape and your audience sees that, too. AirPlay does it all wirelessly, so you can work the room or sit comfortably among the crowd. If you see it, so can they.

The article below will show you how to setup Airplay Mirroring on your Mac.

AirPlay Mirroring in OS X Mountain Lion takes advantage of the hardware video encoding capabilities of 2nd and 3rd Generation Intel Core processors.

Which Mac do I have?

A network

AirPlay Mirroring requires either a Wi-Fi (802.11 a/g/n) connection or an Ethernet connection to the same local network that your Apple TV uses.

Turning AirPlay Mirroring on and off

If your Mac supports AirPlay Mirroring, an AirPlay Mirroring menu extra appears in the menu bar when an Apple TV is on the same network. Turn on mirroring by selecting an Apple TV from the AirPlay Mirroring menu.

Note: The AirPlay Mirroring menu extra icon is blue when AirPlay Mirroring is on

You can also turn it on via System Preferences > Displays

Note: If you don't see AirPlay Mirroring in Displays Preferences, then your Mac model does not support it.

To turn off AirPlay Mirroring, select "Turn Off AirPlay Mirroring" in the AirPlay Mirroring menu extra, or Off in Displays Preferences. You can also press the Menu button on the Apple TV remote to end the current AirPlay Mirroring session.

I hope this information helps ....

Have a great day!
