Post Tiles pulls in the first couple lines of text in a post unless the user defines an alternate excerpt text. Try going back into those posts and adding Excerpt text which describe the video. See if that helps.
I was trying some style changes check again… i dont think its an excerpt issue.

The excerpt code is stopping prematurely so it’s cutting your code short before it closes. Try increasing your excerpt length.
In your code if you view the source it goes like this.
<ul id="post-tiles">
<li>
<a>
<h3></h3>
<script></script>
<div>
<object>
<param>
.... and this is where it gets cut off and the next tile starts....
You need the tags to close before the next tiles tarts otherwise it places the next tile inside the previous tile so on and so forth.
