iTunes movie purchases will not play on external display - HDCP auth error

Hello,

Well, I'm surprised there hasn't been more of a storm over this one already but I expect there will be.

Just got a new MacBook last week and finally found a mini Display Port -> VGA adapter so i could use my 19" external display. I rented a movie from the iTunes store yesterday and when I tried to play it on my external display, it gave me a warning/error that the display was 'not an authorized HDCP display' and it would not play. Plays fine on the small MacBook screen, just nothing external. To make it even worse, i tried all the movies that I have purchased from the iTunes store with the same result... NONE of them will play on anything but the MacBook's small 13" screen. This is crazy unacceptable.

Has anyone else run into this yet or have any ideas of something I may be overlooking in order to get purchased movies to play on an external display?

Thanks!

MacBook unibody C2D 2.0/2.0/160, Mac OS X (10.5.5)

Same problem here as well. I guess they want to be sure we HAVE to buy an
Apple TV.

Not gonna happen.

I'll buy DVD's at my local retailer before that happens.

Great - same story here. Just got my new 2.53 MacBook Pro, after upgrading from a 2.33 GHz MacBook Pro. HD shows I could watch before are now restricted.

So I buy an Apple MacBook Pro, an Apple Mini Display Port to DVI Link, I own an Apple 23" Cinema Display, and want to watch an HD TV show, I bought from the Apple iTunes Music Store.

And yet - I cannot watch it. would I have just downloaded the content from a torrent site, I could watch that file on any computer, using any display.

Brilliant. Makes me happy to be on the legal side.

Not exactly. The Quicktime 7.5.7 update addresses an issue where non-HD iTunes content triggers off the "display not authorized message". I can now play "Terminator 2" from the iTunes Store on my 20 inch Apple Cinema Display. However, the basic issue of not being able to play HD content using the new MacBooks or MacBook Pro's and any external display except the new 24 inch LED's still stands. There'll be no fix for that one. It's just part of Apple implementing HDCP.

You're absolutely correct. I only hope Apple realizes that iTunes video content may start to develop a reputation for being confusing or unreliable when good, non-pirate people start noticing (and publicizing) that they can't view the content they've bought in full resolution on preferred display devices that work just fine otherwise.

I certainly would no longer even consider buying or even renting any iTunes HD content as I use external displays almost exclusively.

They now comply with the intent of HDCP: SD content plays on anything, HD content only plays on displays that are compliant (which is almost none right now).

I'm sure Apple had no choice but to use HDCP to get access to the studio content, but it's our job to publicize that this means law-abiding consumers of HD iTunes content only have conditional access to view that content. Don't feel like upgrading your projector/TV/monitor? Sorry, you only get SD viewing of the HD content you bought even thought your display is capable of showing it.

Maybe eventually, with enough outcry, the studios may rethink this nonsense and allow Apple to sell un-"protected" content, as is done with iTunes+ audio downloads.

+"It's unfortunate that us users have to put up with these restrictions because of all the pirates."+

These restrictions are not in place because of pirates, and have nothing to do with piracy. Pirates do not duplicate movies by sampling the display cable.

Copying a movie from raw DVI signal output is like burglarizing your house through your kitchen sink drain: possible in theory with high-tech gadgetry, but pointlessly difficult and expensive. A pirate can simply rip a DVD by paying a five-dollar rental fee; why would he spend many thousands of dollars on equipment to reliably sample and record differential signalling pairs at MHz character rates? Only then to convert the raw data back to video+audio and recompress?

Piracy is a lousy excuse to make my display stop working; this is not necessary to address any existing piracy threat, or any future threat that may materialize in the lifetime of my notebook.

For me, being able to play HD content from ITunes at all is relatively new and while I would love
for my costly investment in MacBook Pro to pay off in that respect, I can live with Itunes playing
only SD content on my external display. I've lived with nothing but SD for a long time. But I wonder why iTunes doesn't make the movies available in SD in the same way they do the TV shows? Or am I missing something?

OK, all. I saw this the other day:

http://www.macworld.com/article/137148/2008/11/hdcp.html?lsrc=rss_main

I think this says it all about the problems with the new MB/MBP's. As the byline says, not sure if Apple knew this would happen or not. But, to me this explains the problem.

Another trip to the Apple product feedback page seems to be in order for everyone here that feels shorted.

Until then, try to find the prior models of MB/MBP's when they are discounted at
such places as MAC Mall, Power MAX.
