iOS4.3 introduces a buffed-up Air Play and Home Sharing which is really great but if, like me, you don’t have tons of .mp4 files lying around, you might be looking for a solution to play DivX, AVI, or .mkv videos wirelessly from your Mac to your Apple TV. This solution allows you to do just that except that you’ll have to go through an iPhone or an iPad too.

With the arrival of iOS 4.3, developers are finally able to harness the power of AirPlay which means bye-bye HDMI cable from my Mac to my TV to watch videos. Here’s what you need :

• Apple TV 2 fully updated to iOS 4.3 or later
• An iPhone or iPad running iOS 4.3 or later with Air Video installed
• Air Video Server from http://airvideoapp.com

At the time of writing, Air Video costs €2,39 but frankly, it’s worth it. The app is awesome. If you really want to catch a deal, you can always head on over to Appsfire.com and track the app. Update: There’s a free version here but I don’t know if it’ll serve this purpose.

To stream a movie from your mac, follow these steps :

1. Install Air Video Server
2. Set up your preferences and set which folders you want the app to play videos from
3. Make sure the server is On. (Start Server)
4. Launch the app that you bought from your iPhone or iPad, connect to a server (in this case, your Mac
5. Browse to the video you want to play and hit Live Conversion
6. Once the video starts playing on your device, hit the AirPlay icon and send it to your Apple TV – you’re done! Enjoy the show
