Video not playing for client
I have published a module for a client to review, and everything in the module functions for them except for one video. The video is an .mp4 located on a 2nd layer. When the client goes to the "story_content" folder and clicks on the video it plays for them, so it's not that they don't have the add-ins to play .mp4's. It does not appear to be an issue with the video not playing until it's loaded because it doesn't play once it's been open for a while. The file is located on the clients shared folder, and I've tried publishing it to both CD and Web, neither work.
It should be noted that from my computer (the computer it was developed on), I can play it from their shared drive no problem.
Any insight would be appreciated,
