Remove spicific script tags provided by plugins from the head

Hello I have a problem. here is the page to examine the problem.
http://emlmcoach.com/traininglesson/emotionaldetox/lesson1/

The problem is that I am loading jwplayer scripts. But another plugin is also loading jwplayer scripts(older version.)

I temporarily fixed the issue by making the plugins script an empty js file.

I want to remove: <script type='text/javascript' src='http://emlmcoach.com/wp-content/plugins/wp-symposium/js/jwplayer.js?ver=4.2.2'></script>

the script that the plugin adds to the head.
Is there a way to do this?
if i don’t do this, then the next time this plugin is updated, the file will be back and cause the conflict issue again.
