If you're interested from memory Avatar is about 275GB, not sure about in Germany but in Australia the KVM gets emailed out usually the day before first sessions start screening, just a simple case of uploading the key into each projector running the film that week and applying it to the movie that usually arrives earlier in the week.

The fact is they send out the KDM the day before or sometimes the day it begins screening, if a site is having problems with their email server that day or as in this case they just didnt get the keys prepared on time then there's nothing we can do, havent had it happen to us yet but I'm not looking forward to it. Same issue as well if a site has a power cut during a session, the DRM can prevent it being replayed until the next session, with a traditional projector its not hard to fire it back up again, with the digital projectors they're all got to be hooked up to UPS's to make sure it doesnt happen.

Im afraid you can't do that.

No you are.
