I just updated to version 12 of iTunes and version 10.10 Yosemite. I am now receiving the error "This movie can be played only on displays that support HDCP (High-bandwidth Digital Content Protection)." I am playing it on my Macbook Air no external display connected. Help please.

I have exactly the same problem -- MacBook Pro, updated to Yosemite, updated iTunes, can't watch any videos bought from iTunes and get the same HDCP error. (And how on earth is this a "security feature"?)

Me too. Same issue, all the latest update software and OS on a macbook air. Just downloaded the a movie in HD for my upcoming flight in few hours and can't watch it! frustrating.

The issue is from Safari defaulting to HTML5 vs using Silverlight like it did in Mavericks.

So the options are, if you want to use Safari goto your Netflix account, playback preferences and turn off HTML5. This will revert to Silverlight and will AirPlay fine*in Safari.

If you want to use HTML5, just leave the setting for HTML5 on in Netflix and use Chrome, Firefox, etc.

You can't currently have both Safari and HTML5 Netflix when using AirPlay. You'd think Safari would be a little bit more powerful with Apples stances on browser extensions.

I too have the same problem, but I am running a Macbook Air.  Prior to 12.0 iTunes and 10.10 I was able to watch my apple purchases on my computer.  The same movies on the same computer which rendered perfect before, now are producing the error.  This means the several hundred movies purchased through apple store are broken for computer viewing.  As I travel -- this is totally unacceptable.  From my perspective either refund me for all the movies or fix the issue. 

Same problem here. I just upgraded from an old Mac Mini 1,1 with Leopard to the latest Mac Mini running Yosemite and I can no longer watch any of the HD movies that were migrated to the new machine. The old Mac Mini did not have HDMI out and my plasma display does not HDMI in so I can't just do what the dialog says.

Hello Sterling.

Although you tried, I don't believe you answered the question.

I too am getting the same issue.

After the Update to iTunes 12.0 and Yosemite, I am not able to watch any previously purchased tv shows on

my MACBOOK.

No external monitor, no Apple TV.

This is Apple's product and Apple's program.

HELP US!

I get this message:

This movie can be played only on displays that support HDCP (High-bandwidth Digital Content Protection).

I was able to resolve my issue.  I frequently connect my MacBook Air to 2 external monitors - Thunderbolt and USB device.  Investigating the driver for the USB device, I discovered it was outdated.  After downloading the latest SIIG driver and deploying it, I was able to play the movie. 

Recommendation:  If you use any third party peripherals, check that you have the latest drivers.  They will likely not appear during the normal Apple Update process, so you will need to check them manually. 

Hope that insight helps. 

Thank you! This turned out to be the problem for me: In March I'd had used a USB monitor (an AOC) for a while. Haven't used it since, but the driver was apparently still in the system. Tracked down the model number, upgraded, rebooted, and can now watch video again. It's not clear why this affected me when the monitor in question hasn't been attached for months, or when I had no monitor attached at all, but hey.

Drivers are loaded with the OS loads - despite if your external device is being used.  Thus, when iTunes is attempting to display the movie, the driver has the possibility to handle the display and thus causes the conflict. 

Glad it resolved your issue also.  

Getting the same message "This movie can be played only on displays that support HDCP (High-bandwidth Digital Content Protection)." Where do I update these supposed drivers?

same situation but my message in Italian is different:

The selected movie will not play on the monitor.

Can not play the movies on monitors that support HDCP (High-bandwidth Digital Content Protection).

sorry my English translation.

I went onto technical support.  They told me to uninstall and application called DisplayLink.  Once uninstalled all content plays as it should, so in this instance a third party app, was informing the system, a screen with a resolution too low to play HD content was attached, even though it was not.  MacBook Pro with Retina now playing HD content again.
