Here’s AirPlay working on the new Apple TV streaming from an iPad. It works great in Apple’s Video app and YouTube, but I can get audio only to work in iTunes — video isn’t working.
When I select the AirPlay popup, it shows a speaker icon for the AppleTV — not the normal screen icon. Audio streams fine but it won’t play video. Puzzled.
UPDATE: It’s audio only in Netflix too.
UPDATE 2: It looks like video playback is disabled in certain apps, including iTunes on iOS devices, which is more of a storefront than a multimedia app. Video bought through iTunes and played back through the iPod app on an iPhone (and the Videos app on an iPad) work fine. Jason Snell at Macworld had the same experience.
