Brightcove video code snippet keeps disappearing

Whenever I copy and paste some Brightcode video code into the HTML window of a wysiwyg field, it allows me to save it, but when I view the live page, the video dosn't appear. Then, when I go back to the CMSB page, most of the code snippet has disappeared, and only a portion of it remains. Any idea why this might be? The video appears if I drop into place manually.

This is the Brightcove code I'm trying to add via CMSB:

<!-- Start of Brightcove Player -->

<div style="display:none"></div>
