RSS Feed Validation Issue

I recently launched a new version of my site (DivvyHQ.com) and my URL structure changed a bit from the previous version. When I went to Feedburner to update my feed URL, I received the following:

The URL does not appear to reference a valid XML file. We encountered the following problem: Error on line 269: The content of elements must consist of well-formed character data or markup.

Hmmm…So I went to the W3C Feed Validator to analyze the issue. The validator returned 9 errors, all of which appear to be resulting from the HTML5 jquery player code that loads from the shortcode. Here’s a copy of the error report, but it would seem that the last error (line 269) is the main issue.

Sorry…This feed does not validate.

– End of report

So…Need a little help here. Not sure how to proceed in order to get this cleaned up and validated. I’m not a programmer, so go easy on me. I know enough to be dangerous.
