NetFlix is having issues with DRM controls and Android security (Or lack of) Hulu is available and other streaming apps are available. The problem with Hulu is that it is a Hacked/Kludge pull from a Phone, Not the approved version yet. I think the reason is basically the same. DRM and rights.
Data Rights Management (DRM) hate it or loath it is a cause for many streaming or even Library book use problems or unavailability.
