I think the idea of the checksum is to avoid loosing metadata when
videos are moved. What is supposed to happen is if a video is moved
within the file system then MythVideo should detect that and update the
location of the video in the database keeping the original metadata
intact. If you think it's broken why not provide a patch to fix it,
clearly you have the ability?
