Help with video-js video player code

I have video-js code on a web page. I have that code several times on the same page. It all plays successfully in Chrome, but in IE11 while a few players play their video(self-hosted), I see this “The video player aborted due to corruption problem or because the video used features your browser did not support” in a couple of players.

And in Firefox 37.0, I see this:
“A network error caused the video download to fail part-way”.

I suspect something simple in the code is a bit off.

Do you know the solution? I look forward to any comments/insight/solutions.
