I know there are many threads on hdcp issues. 

 

I'm trying to AirPlay hd movies I've bought on iTunes from my ipad through Apple TV to my HDTV.  With some movies (Rise of the Guardians for example),  I get the "this movie is not authorized to play on this display" HDCP message.  I realize I can play the movie right from iTunes on my Apple TV.  However for movies that we watch multiple time (kids movies mostly), the Apple TV really crushes my download limit with my ISP.  In theory I can download once to my ipad and AirPlay watch it multiple times right?  My tv and my receiver are definitely HDCP compliant, so that's not the issue.  Why can't I AirPlay these with my ipad but its no problem with Appletv.  Do I have to resort to the hdmi adaptor for the ipad?  Why?

    To start with if you are using Airplay Mirroring don't bother as it will degrade quality.

     

    I suspect however you are using 'push' Airplay to send the downloaded stream to the AppleTV.

     

    Are AppleTV AND  iPad connected to the internet?  If not they need to be - Apple has quite stupidly (probably for rights reasons) does not allow Airplay of a protected movie without 'authorisation' - this would entail a quick inernet connection to Apple's servers to ok it and would not use any significant internet bandwidth.  The annoyance here is if you go on holiday/vacation with iPad/iPhone with media and a compact AppleTV, then an internet connection is needed to play to AppleTV via Airplay. 

     

    Your best option if you have a computer is to have the content downloaded to iTunes (sync it from the iPad using Transfer Purchases) on the computer and stream it across the LAN from there.

     

    A computer running iTunes on the same network as AppleTV will allow AppleTV to 'pull' the stream from the computer without using internet bandwidth provided you access it using AppleTV's Computers icon.

     

    If you play back purchases from the cloud using Movies/TV Shows icon it will assume you want to stream from the internet and use all that bandwidth again.

      Sometimes I get audio with no video.

    If that's from certain apps then it's likely a 'rights' issue and the app developer only allows audio airplay - check their website/faq.

    Both devices were connected to the Internet, so I still don't know why the basic airplay doesn't work.

    Yes, it should work so long as they are on the same LAN.

     

    I suspect you'll find streaming from conetnt in iTunes on the iMac will work fine.

     

    The iPad HDMI adapter actually works pretty well, just make sure you get the correct one for your iPad if you go down that route.
