HBO is supported as is Starz, more recently Amazon Video, CW, Hulu+, TNT. SyFy, Showtime are not. Those two play the audio, but not the video. It can't be because of a video format issue because Apple TV USES iOS and if an app plays audio and video on an iPad, it should work over Airplay, right? And it's frustrating when a video will play on a content owners' web site (AMC) in a browser, but not on iOS apps or web browsers. Does Chromecast have these issues? Cantream ANY content from a Chrome browser to the Chromecast dongle?
