I'm going to have to get on a soap box here for a minute because this is just beyond retarded.
A theater runs an advance "security" screening of a movie digitally.
Said theater receives the content via a hard drive 5 days before the show. Is this a security threat? Absolutely not, because the KDMs (keys to unlock the content so it will play) haven't been received, nor are they valid except for the very short window of the screening anyway.
When the screening is over, the security goon DEMANDS to "watch the content be deleted".
So yeah, ok fine...whatever. Here you go buddy, watch and behold POOF! Yay its gone, who cares? (I sure don't, because I have a brain and understand how the KDMs work.)
Now lets analyze how retarded that is. The theater had the hard drive in their possession for 5 days. Lets just PRETEND FOR A MINUTE that someone actually wanted to copy the content, knowing damn well that there was no way to actually VIEW the content...the theater had FIVE DAYS TO DO IT, INCLUDING THE TIME THE MOVIE WAS ON SCREEN!!!
But again we are left with a dose of reality, even if someone had 50 copies of a security screening hard drive...big whoopdie fucking do! It is USELESS!!!
...or are they telling us the super-encryption actually a big load of bs and cracked without TOO much difficulty???
Ok I'm done. I just had to vent because I really take offense to being treated like a criminal.

Ok, This topic is becoming an "ISSUE" all round.
The control of digital content is taking a long time for the distributors to get their heads around it. Especially outside the US where its all new for the distributor regional offices.
As a test site in which we develop tools for Digital cinemas, we have gotten our hand slapped for simply keeping a copy of a DCP on a Library system!!
DCP's are easy to copy and move around, however, the distributors still think of them as PRINTS. The fact you can copy them, scares them. It will take them some time before they actually understand how this all works.
What we need to do is to try and operate as close to how they want as possible for the near term. As they learn, they will realise that it is not the distribution of the DCP that is of any major concern, but the KDM's themselves.
In the long run, once they understand the level of security a DCP really has, and how usless they are without a KDM, they will probably relax a little.
But until then best to work with them.
For example, if (or when) you receive a broken DCP drive, do not run to your friend and get a copy of them. Be sure to report any issues to the distributor first and get them to make the decision of how to rectify the issue. They need to feel they have control, (Which they do as they control the KDM's but they need to realise that.)
This also brings in the point of, as soon as you receive a DCP, ingest and verify it. If it verifies you now you have it as it was created. If its faulty, it if faulty for everyone. Only a KDM and viewing it will show that.
