How to Prevent "Buffering" Message after Playback

We're using the new FMS (or AMS, sorry), video delivery method which incorporates manifest files to play back f4m files.

Works great, I especially appreciate being able to view the videos on iOS devices.  One caveat...

After the videos play, I always get a little box that pops up in the center of the screen that says "Buffering" , with a little loading-type animation that goes with it.

Is there a way to prevent that "Buffering" message from appearing?  It makes it appear that there's more video yet to play, or another video is about to start, etc. 

Any tips on prevening the appearance of that Buffering message?

Thanks!

How do I prevent the above from appearing at the end of my videos?
