Apple DVD Player’s Way of Failing Silently

Our media collection contains a number of DVDs whose region code is 2, because I had bought them when I was still living in Germany. The region code of our DVD player is 1, though, and unfortunately, it is one of the few models for which you can’t find an unlock code online. (Here’s an older blog post, dating back almost ten years, on how simple it usually is to change a DVD player’s region code.)

For reading legacy CD-ROMs, we use an external USB optical drive with our Macs, so I decided to try the following route: set the external drive’s region code to 2, play movies with the DVD Player application on the Mac, and stream audio and video to our TV via an AppleTV using AirPlay .

A map view in DVD Player's preferences panel shows the six geographic regions and their codes. It also displays the region code of the DVD that is currently in the drive, and the drive's own code.

Things looked promising — until I activated AirPlay on the Mac: While the computer’s desktop was mirrored on the TV, and the movie’s audio played through the TVs speakers, a gray rectangle had replaced the video viewport in DVD Player.

The Mac's desktop, showing the DVD Player video window with all the controls, like timeline, playback control buttons, etc. In this case, though, since AirPlay is activated, there is just a even gray rectangle in the window instead of the video signal from the DVD.

To sort out the problem, I connected the Mac directly to the TV via an HDMI cable. Interestingly, that changed the display resolution, but the movie did appear on both the internal and external screens.

Third-party software to the rescue

Next, I opened the DVD in VLC Player and tried using AirPlay again. Now, finally, everything worked as intended: The video and audio played on the Mac’s screen, and both were properly streaming to the TV using the default resolution.

The same setup as above works just fine with VLC Player, a third-party video player application. Its main window properly displays the video stream, even when AirPlay is activated and streaming to the same destination.

Considering that the video was grayed out in DVD Player as well as in my screenshots, unless I was using VLC Player, leads me to believe that Apple intentionally blocks playing DVD movies via AirPlay for “copy protection” reasons. Being able to stream HD videos via AirPlay from iTunes without any hiccups is further indication that this is not a technical issue, but a conscious design decision.

Failing silently is among the Mortal Sins of UX Design

Enough has been written about how “Digital Rights Management” punishes honest, paying media customers.

The annoying aspect about this particular experience, however, is the utter lack of meaningful feedback: How about popping up a dialog box that states that, “For copyright reasons, you cannot stream a DVD via AirPlay”? In fact, that message could appear right inside the DVD Player video window where the user is looking for the now-missing video signal.

Instead, all you get is a gray window where the movie used to appear.

Failing silently like this will lead users to wonder whether there is a technical problem, and likely make them trouble-shoot their setup, and search online for more details on the issue. Apple could easily avoid this waste of time and effort by showing a simple notification — even if that might come across as somewhat embarrassing for a company that takes an outspoken (and highly commendable) public stance against “copy protection” mechanisms.

Error Messages in Bounced Emails

Error messages are always annoying, but designers and developers can make them less painful by addressing three questions (in a language that is meaningful to their users):

  1. What went wrong?
  2. Why did it go wrong?
  3. What can the user do to fix it?

This applies to all error messages, regardless of the context in which they appear. Case in point: Messages that mail servers add when they reject — or “bounce” — an email.

Feels like email support purgatory

When I tried to send a command to an email list server a few months ago, the email was rejected with this error message:

SMTP error from remote mail server after initial connection:
host [REDACTED]: 554 [REDACTED] ESMTP not accepting messages

The message text makes it sound as if this server is not accepting any messages. But then there’s the 554 error code, which is commonly used when a server rejects an email which it considers to be spam.

To fix the problem, I contacted the help desk at the university that hosts this list server, using their publicly accessible website.

They responded via email, saying that they had assigned and update the support ticket, and included a link to the ticket on their website. After clicking the link, I was asked to sign into the university website — which I couldn’t do, since I was not a student there and, thus, had no account for the site.

My direct email response bounced as well, so I had to open another ticket to follow up with them. In response to which I received another update email with the same kind of useless-to-me link. So I submitted yet another support ticket, explaining to them the original problem; that my direct responses to them bounced too; and that I could not sign into their support website, either.

Although they had already received complete headers from my original email and from the bounced response to their help desk’s email, their next response said:

Please attach or copy/paste the original message to the ticket so we can review of [sic] troubleshooting purposes.

Picture me, sitting in front of my computer, a desperate look on my face, flailing my arms wildly, and screaming, “BUT HOW?!”

So I simply gave up.

My original email just wasn’t important enough that I would endure this nonsense any longer.

A clear and simple path towards un-blocking your emails

A more meaningful error message for the exact same condition (namely that the receiving server intentionally rejects an incoming message) is this one from EarthLink:

SMTP error from remote mail server after MAIL FROM:[REDACTED] SIZE=2379:
host [REDACTED]: 550 IP [REDACTED] is blocked by EarthLink. 
Go to earthlink.net/block for details.

It clearly explains the issue, and does so in a language that does not require in-depth IT knowledge to understand. More importantly, the page that the included link points to answers the three key questions listed earlier:

  1. What went wrong,
  2. why it went wrong, and
  3. what you can do to fix it.

The EarthLink page provides detailed information, starting with a

While it was still a bit of a hassle to have our server removed from EarthLink’s black list, the error message and the support page provide enough information to understand what to do next.

An essential component of this process is that the admins at EarthLink provide an email address — blockedbyearthlink@abuse.earthlink.net — that does not block any incoming messages. It’s this detail that makes direct email communication with the support team possible, so that the workflow is much more convenient and efficient than what the above university had to offer.

Addressing rejected emails the Google way (and it ain’t pretty)

Alas, sometimes even a meaningful error message and a link to further information still doesn’t suffice.

For reasons unbeknownst to me, Google has been considering me a spammer for the last couple of months. Emails to Gmail accounts regularly end up in the recipients’ spam folder, even though the messages’ contents don’t feel at all “spammy” to me. We also never found evidence (in the log files, etc.) of spam emails being sent from the root server that we share with some friends.

This problem has gotten to the point where Gmail has rejected my emails outright. The error message that was contained in the responses is very well-phrased, and it also contains a link to further information.

Delivery to the following recipient failed permanently:

    [redacted]

Technical details of permanent failure: 
Message rejected by Google Groups. Please visit 
http://mail.google.com/support/answer/188131?hl=en
to review our Bulk Email Senders Guidelines.

This does not make sense, though: The messages were sent to individual Gmail accounts, not to Google Groups, and they did not originate from an account that would even remotely qualify as a “Bulk Email Sender,” either.

Following the link to their support page provides an “outstanding” example for what I think is the biggest flaw in Google’s overall philosophy.

Under the heading,

For Google, there is a solution to every problem — but it is always a technological one.

If you have any problems with a Google product as a regular user, you can’t simply call a human at a support hotline. Instead, you’re referred to a support forum, which is often maintained by other users (but no official Google representatives), or you’re offered another tool to help you fix the problem you have with the first tool.

Same here: The help page explains perfectly well what happened, and why it might have happened. But the question “what do I do now?” is “answered” by pointing to the Gmail Postmaster Tools.

The

The help page for these Postmaster Tools states that this is for you, “[i]f you send a large volume of emails to Gmail users.” What, then, if it’s been only a handful of emails that were rejected, as in my case?

What’s more, the Postmaster Tools can only be used if you have your own domain. So what do you do if you use another large email provider like, say, Yahoo! or Hotmail, without your own domain?

Considering how many companies are using Gmail as their sole email service, not being able to reach these companies, because Gmail blocks your emails for some obscure reason, is not just annoying, but actually a bit scary.

Not having any way to easily fix any blocking, though, is just unforgivable, especially when we’re talking about a modern-day IT giant with a resource pool like Google’s.

Two of my rejected emails were job applications. I don’t know what, specifically, was wrong with them. But I do know that I have no alternative communication route into these companies, short of stalking their employees online. All because Google does not let me contact a human support person to help me solve this.

And people ask me why I am so critical of Google sometimes.

Downloading Speaker Slides from a Conference

Last month, my wife and I attended the O’Reilly Design Conference in San Francisco. The conference offered great keynotes and presentations, and the venue — Fort Mason Center — was spectacular.

O’Reilly has compiled a list of the event’s keynote videos and speaker slides. Some slide decks can be downloaded directly from that page, while others are hosted on Speaker Deck or SlideShare. The workflows for downloading the decks from the latter two sites create surprisingly different user experiences.

Speaker Deck: “Click. Done!”

On Speaker Deck, the prominent “Share” section contains a Download PDF button. Click that button, and the PDF file instantly opens in the browser, from where you can easily save it to your computer. Alternatively, you can right-click on the Download button and directly download the file via the context menu.

Clean, quick, easy. Nice!

SlideShare: “No account? Not signed-in? No PDF!”

SlideShare’s Download button is just as easy to find.

Click it, though, and instead of just starting the download, you see a dialog box about “Clippings.” At this point, I was just trying to download the file, so I chose to “[c]ontinue to [the] download.”

Clicking the link underneath the button does start the download — if, that is, you are signed into SlideShare. If you aren’t, you are requested to log into the site.

That, of course, also means that if you don’t yet have an account for SlideShare, you have to sign up for the site before being able to download any of the slide decks. At least the triggered download will start automatically once you’ve completed the login procedure.

Cumbersome by design

You can often hear designers and users complain about LinkedIn’s user interface, and it is LinkedIn that owns SlideShare. This simple download workflow is a good example for a less-than-stellar design decision.

Note how the clippings dialog box does not have a “Don’t ask me again” checkbox. And indeed: every time you decide to download a slide deck, that process will be interrupted by having to make the decision fore or against clippings. Every single time.

Worse yet, even if you adopt that feature by clicking Start clipping, and clipping a flew slides “just to be sure,” the dialog box will still appear whenever you click Download. In other words, even when the dialog box has done its duty, it will still come back time and again.

Who controls the content that you own?

This odd behavior aside, there’s a deeper, more philosophical issue to think about here.

Websites like SlideShare or Speaker Deck don’t own their users’ works, they just host them.

What does it say about a company, then, that they require you to have an account with them before you can access hosted content that, say, a conference speaker has made available? Why did Speaker Deck decide to make this process as painless as possible, while SlideShare uses it to attract new users? What would SlideShare lose by allowing a direct download without requiring visitors to log in?

And finally, does a conference speaker’s choice of provider reflect back on that speaker, because this download process might be perceived as being part of the overall presentation experience?

That said, from this conference attendee’s point of view, the most desirable option for this workflow actually is finding a direct download link to the PDF files right on the conference website. It doesn’t get much more efficient and convenient than that.
