[DCP-o-matic] DCP convertion from AVI

Hi DCPomatic, I am Jax from Singapore. Recently I am preparing a proposal video and planning to play it in a cinema movie hall, the cinema manager said I have to convert my video to DCP format. I did use DCPomatic to convert my AVI video, but after the convertion, what software I can use to run the video? And when I use Windows Media Player to play it, there are only video but no sound. May I know what cause this problem? Thanks Best Regards Jax
