[DCP-o-matic] CPL + assetmap document properties.

Hi, I have problems loading dcp’s into our dcp player (Kodak JMN-3000, old but still works). Both Interop and smpte have the same problem. Strange thing is that it did load dcp’s created with dcp-o-matic in the past. I made a dcp of a feature film containing 5 reels and subtitles, also in reels. This is the error the dcp player gives me: ‘Required CompositionPlayList document property is missing’ (It gives this for every reel, so 5 times). ‘Required AssetMap document property is missing’. Anyone has an idea? Thanks, Tom
