[DCP-o-matic] DCP question

Hi, Thanks so much for the free software - I will make sure we donate towards it. I do have a question regarding the making of DCPs - we are struggling with creating them for a cinema. The bottom right hand side of the DCP when projected on to the screen curves up a little. Could this be to do with not converting the DCP into the correct ratio or the fact the cinema has a curved screen? For example a 1.78 ratio DCP has been made into 2.39 scope as I thought it selected them automatically. I hope you can help me understand.
