From the article:
When we went to our seats, the wait staff let us know that despite the fact that the previews were playing, we wouldn’t know until the movie actually started whether we could see the film or not. If it didn’t work, the screen would just turn black. Luckily, the film went through without a hitch.
Not familiar with cinema projectors, but as I have gatherered from this forum problem is caused by KDM (used to decrypt movie) provider / reseller called Deluxe. Neither Sony or this cinema chain is at fault and problem indeed seems worldwide.
Find it very hard to believe to be honest. Could this be simply some rumour from colleagues? Doubt any vendor would implement anything like this, drives could be simply encrypted to protect data if they ever get stolen.
Yes, I deal with KDMs weekly but I’m not for sure if this issue was KDM related or if it was certificate related. As for the service destroying themselves, I’ve never personally seen it happen, but I’ve been told by upper management that they’ve seen it happen twice. I don’t really have any way to verify the information but it wouldn’t surprise me and I don’t see why anyone would make that up unless they really don’t want people messing with it, but it seems like such an unlikely scenario.
