Netflix Axes Apple AirPlay Support (cnet.com)
If you stream Netflix on your iPhone or iPad, the app will no longer support Apple AirPlay. A report adds: This means that you won't be able to cast shows on Netflix from your iOS device to your Apple TV. Netflix's note says AirPlay is "no longer supported" due to "technical limitations." "With AirPlay support rolling out to third-party devices, there isn't a way for us to distinguish between devices (what is an Apple TV vs. what isn't) or certify these experiences. Therefore, we have decided to discontinue Netflix AirPlay support to ensure our standard of quality for viewing is being met," a Netflix spokesperson said in an email.
Presumably it has much more to do with being able to Airplay a perfectly viable compressed bitstream to an uncontrolled device that could be recording it or doing anything else with it (whereas Apple tended to respect the DRM etc.).
Airplay->MP4 anyone? I'm sure it's possible.
The in-room TV did have direct support for a few streaming services (including Netflix), but I'm a bit hesitant to be entering my Netflix password on an untrusted public device.
Netflix still supports Chromecast, what part of your setup did they stop supporting?
