DCP-o-matic

I have created a DCP with the content type set to Trailer when it should have been Short. As shorts go it's quite a long one, so I don't want to re-do the whole job from scratch if I can help it. What is the best way to fix this. We will only be showing this once, but I will be sending it on to another cinema, so I want the content type to be correct.

DCP-o-matic isn't great at this, but you can import your DCP into a new project, fix the content type and re-make. It should go as fast as your discs will allow.
