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 Investigating the driver for the USB device, I discovered it was outdated.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.

I used finder and could not even find that app. How did you accomplish this?

Yet I can not seem to find the app DisplayLink

sorry my English translation.

I don't play my iTunes movies very often on my Mac so I don't know how long the problem may have been in existence. However, my (our) issue is now occurring and I am receiving the error message,

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

I have tried every solution that I am able to on my Mac, unsuccessfully. Before I contact support I thought I would make a post to see if anyone has a newer or more novel solution I can try.

OS X Yosemite

Version 10.10.1

iMac (21.5-inch, Late 2012)

3.1 GHz Intel Core i7

16 GB 1600 MHz DDR3

NVIDIA GeForce GT 650M 512 MB

Regardez,

Help, please!

Where in finder can I find those plugins? I'll try just to erase it since I don't need it anymore.

After several sessions with Apple Support we isolated the problem. I use the Microsoft Remote Desktop to communicate with a Windows run laptop in my home office from my Macs. The program is not downloaded from Apple apps (The only one for Mac to Win comms *****.) but from Microsoft's Support site. The fapp could have become corrupted but, more likely, had been superseded by an update but I do not believe I would have received a notice from Microsoft.

In either case, I deleted the app and two helper files in the Library and the movies finally were playable without an error on the Mac. Please note that we had previously trashed the app with no joy and succeeded only after we trashed it again but with the two files in the Library. I downloaded the app from Microsoft, performed a clean install and everything is working perfectly.

My suggestion is that if you have any app that shares another screen or monitor somewhere then you may wish to uninstall it and reinstall a clean copy.

This is, obviously, only a limited solution for this error.

I am having this same error: HDCP (High-bandwidth Digital Content Protection). This is on a brand new iMac with the 5k retina display. Movie played fine on it when first tried them out. now they won't play. I am not or ever connected to any external device, windows lap top or anything else. I am playing or trying to play back the movies or tv shows directly from iTunes on my iMac but get this error.

I am having the same problem. have had macbook pro 2.8 Core i7 late 2015 13inch with Retina and as soon as I upgraded to the latest version of iTunes my brand new dell P2815Q has been giving me this error. It was working fine until the iTunes upgrade now can't see any of my HD content that I bought from Apple.

I have this same problem on my MacBook Air. Movies and TV shows I purchased FROM ITUNES will no longer play now that I have upgraded to Yosemite. I have been on the phone with Apple Support and a super tech of some kind and they have had me install and uninstall lots of things and NOTHING helps this problem. The message I receive - just like everyone else on this forum is:

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

There is some sort of fix that Apple needs to provide to rectify this issue. The Tech support person had me capture the message and all kinds of files and send them in - and I've been waiting for a week to hear back. Something. Anything. This has nothing to do with an external display. And I cannot find 'displaylink' on my computer. It is just myself and my MacBook Air. I might expect this from a Windows machine, but not my Air. 😟

It was the displaylink software for me as well. I found the displaylink uninstaller via spotlight, ran it, and magically everything began to stream again without the HDCP error.
