Adding Videos to DLC

We are trying to create a mobile app that has multiple videos that need to be placed into DLC files. We have tried adding them using chunking and we have tried added them as plugin dlc. If we use chunking the video file doesn’t get put into the dlc as there is no way we could find of tagging the video as it has to live in the Movies folder. If we use the plugin dlc method and place the video in the plugins Movies folder it packages in the dlc, but we can’t access the file using a file media source during play. Has anyone run into this and found a solution?
