BE Won't play video - Uncaught TypeError: undefined is not a function

After adding a video to a post, I am unable to play the video when viewing the page. I see the player box (screen area with play, track, time, and mute controls), but pushing play doesn't do anything. The home page and the post both have the following error:
Uncaught TypeError: undefined is not a function
which points to the following code:
jQuery(document).ready(function($) {
$('audio.mep, video.mep').mediaelementplayer({defaultVideoWidth:480, defaultVideoHeight:360});

I have seen other posts about this which suggest to ensure that jQuery isn't being loaded twice and when I did a search of the dom for jQuery, I don't see any duplicates. Here is my javascript include list:

In the HEAD tag:
<script type="text/javascript" src="/blog/Scripts/Auto/01-jquery-1.9.1.min.js"></script>
<script type="text/javascript" src="/blog/Scripts/Auto/02-jquery.cookie.js"></script>
<script type="text/javascript" src="/blog/Scripts/Auto/04-jquery-jtemplates.js"></script>
<script type="text/javascript" src="/blog/Scripts/Auto/05-json2.min.js"></script>
<script type="text/javascript" src="/blog/Scripts/Auto/blog.js"></script>
<script type="text/javascript" src="/blog/Scripts/App/widget.js"></script>
<script type="text/javascript" src="/blog/Scripts/App/qnotes.js"></script>
<script type="text/javascript"   src="/blog/editors/tiny_mce_3_5_8/plugins/syntaxhighlighter/scripts/XRegExp.js"></script>
<script type="text/javascript"  src="/blog/editors/tiny_mce_3_5_8/plugins/syntaxhighlighter/scripts/shCore.js"></script>
<script type="text/javascript" src="/blog/editors/tiny_mce_3_5_8/plugins/syntaxhighlighter/scripts/shAutoloader.js"></script>
<script type="text/javascript" src="/blog/editors/tiny_mce_3_5_8/plugins/syntaxhighlighter/shActivator.js"></script>
Immediately before the problem inline script:
<script type="text/javascript" src="/blog/Scripts/mediaelement/mediaelement.min.js" defer="defer" async="async"></script>
<script type="text/javascript" src="/blog/Scripts/mediaelement/mediaelementplayer.min.js" defer="defer" async="async"></script>
I have also seen other posts which suggest to turn off optimization, but optimization was already turned off for me. I turned it on to see if it would make a difference and it did not. I also played with the "Compress WebResource.axd" and the "Enable HTTP compression" settings and they didn't seem to do anything with regards to the issue either.

Did you ever figure this out? I went to upgrade to 3.1.1 and have the same issue you are having - but I don't get the error with current BE 2.9.xx

I'm sorry, but I did not. I ended up having to inject my own html rather than use their video widget. It's a pain because it means the business users have to inject html rather than use the interface. And, there are some problems with that because if you edit a post that has this html injection, it will try to revert it to what it thinks it should be and that messes it up also.
