Late to the party - but in Maverick, check your screen resolutions. Make sure your display panel shows Resolution higher than the minimum HD resolution (anything higher than 1080). Mine had automatically selected the "Best for Display" setting in Maverick and suddenly my Samsung synchmaster screen was giving the HDCP error. Reselecting 1920x1080 gave me back my screen for HD!
Bought and watched HD movies without any problem on Mac Pro with 27" EIZO monitor. Suddenly I started getting this HDCP error message. I did ALOT of actions, trying to resolve this problem. Finally called apple support and went through more steps with the technician on the phone. Spent almost half a day with the result that it didn't change anything.
The steps included the usual things like permission repair, emptying all the caches, reseting user permissions, setting up a clean new user, reinstalling 10.8.5.
At that point, the apple support said he had to forward it to the engineer.
I played around with it some more and tried with an old acer monitor. A very cheap monitor, I think 24" and the HD movies played with no problem!
I tried again with my EIZO. No luck. I then played around with the resolution an found out, that the HD movie show when I LOWER the resolution. It does not work on any resolution higher than 1920 x 1080 but works all the way down tp 800 x 600. The native resolution is 2560 x 1440.
I still should here back from apple. I will write here again if I get any news.

The High-bandwidth Digital Content Protection problem just struck me too.
I have an iMac 27" 2009 model 8GB memory with Mavericks and iTunes 11.1.3.
I have 9 episodes of Breaking Bad in HD all of which have 1 or more plays with nary a problem.
Last play was 8-November.
Suddenly today I can't watch any of them with this newly minted problem!
Then, I quit a background video process.
They play again.
So, it must (may) be related lack of sufficient resources (processor, memory, etc) to play the video.
I was quite unhappy for a few minutes. Faith restored. Forgive me for doubting!
I echo rkachel - "quit a background video process" triggered me to realize I was using 'screen sharing' to the mac mini that had the HDCP problem and as soon as I quit that the problem went away. Fortunately I only lost an hour but no $ chasing other possibilities. I wish apple would give a clearer message, perhaps a list of video output devices it recognizes at the moment that aren't HDCP?
I want to record my two cents...
Just got off the phone with Apple.
I purchased the Sound City movie in the HD format a year ago. At the time I tried to display the movie on a 23" Apple Cinema Display. It would not play. It played on the laptop display only. It gave a dialog stating that other hardware was required to display the file.
At the time, I had seen the film in the theatre. So this particular issue, though it was annoying to discover it was not pressing, so I did not pursue a solution from iTunes.
Yesterday, I decided to rent "Why We Ride" from iTunes. This was the SD version. The download encountered an error. In my interrogation I tried launching Sound City HD while the 23" display was connected and was reminded that the movie would not play there.
Today, I tried to get support from iTunes to resolve this. And they did nothing for me. They stood firm regarding the length of time that had passed. I asked them to swap out the HD for the SD. No dice. All sales are final.
Apple if you are listening, this customer is done. I will never buy or rent anything from iTunes ever again.
It's just entertainment. There are many alternatives for obtaining content in the future.
I had the impression my Apple equipment was capable of displaying all the products in the iTunes catalog.
This is a hard lesson. But one well learned.
For what it's worth, I was experiencing a similar problem attempting to view an HD movie (Thor: The Dark World) on a Win 7 system. After receiving the same "Display not able to blah blah blah" and reading the entries here, I decided to try fiddling with the display resolution on the monitor.
The native resolution for the monitor is 1920x1200 and was set accordingly.
I lowered it to 1920x1080 and again tried starting the movie and it then played.
Oddly enough, I reverted the resolution to native during playback and the movie continued to play without issue.
So, before jumping through a series of hoops, some of which are on fire, try dumbing down the screen resolution to 1920x1080 if it is set greater than that.
I had this problem and I'm using a new HDCP compliant external monitor, with a Mini-Displayport to HDMI adapter with my 2013 Macbook Air, and an HDMI to DVI cable plugged in to that (that's what my monitor came with!). I could have sworn that I tested these iTunes videos when I first set up the monitor and it had worked, which is why I found this thread. I can confirm that just changing the resolution of the display to 1600x900 and then changing it back to the native 1920x1080 solved the issue. iTunes now plays movies without showing the HDCP error.
I have exactly the same problem in combination with an Apple 24" LED Cinema Display which is definitely HD capable. However, I can not confirm that changing the resolution to 1600x1000 and back to 1920x1200 will fix the issue. At least it did not for me.

None of the suggestions worked for me as I could no longer play movies in iTunes on my MacBook Pro nor iMac 27" ... Apple support had me remove a package called DisplayLink. Goto upper right hand corner and click spyglass and type "display" ... I saw "DisplayLink Uninstall" and double clicked that to remove it ... After a reboot, I was able to play my iTunes Movies. This package is installed in one of two ways: 1) A Dell monitor 2) A software package that enables sharing your screen. Either way I had both of these items and this package was installed as a result.
THIS IS THE SOLUTION TO THE PROBLEM. I have been searching for days and was getting quite frustrated that my purchased video media, all quality levels was not playing in the iTunes player. I found this post and opened the spotlight search and lo and behold, that displaylink thing popped right up. Once I uninstalled and restarted, VIOLA! Like magic my videos are playing again! Apple should post this fix at the top of the thread! Stupid displaylink!
After upgrading to Yosemite I suddenly started getting the HDCP error message for music videos (some, not all) and certain movies I purchased and played many times on my iMac 27" through iTunes previously without issue. Unfortunately I searched for DisplayLink but it wasn't on my machine so I had to look for something else. I tried the change of display resolution but that did nothing.
I reset the SMC i.e. Shut down, unplug anything connected to the machine, unplug the Power cord, leave for about 15 seconds and then reconnect and restart. Seems to have done the trick. Simple solution and hopefully equally applicable to the other circumstances described by those getting the HDCP error message.
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.
