Checkerboard pattern when playing DVDs over AirPlay

If you have an Apple TV attached to a TV or projector in your classroom, you may have had trouble with some DVDs when using Apple DVD Player. You’ll see nothing on the TV or projector, and on the Mac you’ll see a checkerboard pattern where the video window should be.

This is a “feature” of Apple DVD Player, designed as a copy-protection measure. To make Hollywood movie studios happy and limit piracy, Apple prevents the transmission of copyrighted DVDs to AirPlay devices.

The easy workaround is to use VLC player instead; it should already be in your Applications folder. Simply drag your DVD on top of the VLC app, and it should start playing the DVD for you. Some versions seem to have trouble with audio. If you can’t hear audio on the TV or projector, just restart your Mac and try again; audio should now work correctly.

If you’re having any other problems with your Apple TV connecting with your Mac, please do file a work order and we’ll look after you as soon as we can.

Non-responsive Apple TV

If your Apple TV is not responding to button presses on its remote, but you can see that the little white light on the Apple TV flashes when you press a button, it may need to be “power cycled”, or turned off and then on again.

From time to time, Apple releases updates for your Apple TV’s operating system. Most of the Apple TVs in the District are set to automatically apply these updates when they become available. However, in some instances, the update doesn’t take and your Apple TV is left in the state described above.

All you need to do is disconnect the Apple TV’s power cable, either from the wall, or the back of the Apple TV (whichever is easier for you), and then plug it back in again. The Apple TV should finish booting up properly, at which point it will start working normally.

If not, do file a work order and we’ll stop by to check it out for you.

SMART Board and Epson projector alignment

Has the image on your SMART Board gone wonky? Is your SMART LightRaise 60wi no longer projecting a “square” image on your white board? Is your Epson showing something closer to a trapezoid than a rectangle?

We’re happy to fix this for you! Just file a work order under the Multimedia & A/V category, and we’ll come by and realign and recalibrate your system for you.

Please, don’t attempt to “straighten” the projector yourself. There are actually several adjustments to make, and some may be locked down. If you force the projector, you can strip the locking mechanism, necessitating costly repairs which would require your projector to be sent back to its manufacturer.
