title: Youtube Flash embed flickering in Firefox
body: <p>I'm having a problem with youtube video embedding;</p>
  
  <p>In some places on my site (like news etc.) video is normally displayed and can be watched, while in others (forum topics mainly) it flickers whenever I mouseover it (making a new HTTP request to YouTube, as I can see in Firebug). </p>
  
  <p>It definitelly has something to do with CSS rendering; when I disable JS nothing changes but disabling CSS causes it to work properly.</p>
  
  <p>Firefox version: 3.6.12
  Flash version: 10.1.82.76</p>
  
  <p>The code I'm using for embedding:</p>
  
  <pre><code>&lt;object type="application/x-shockwave-flash" width="390" height="293" data="http://www.youtube.com/v/pIxVoDNbujM?ft=18"&gt;
      &lt;param name="allowFullScreen" value="true"&gt;&lt;/param&gt;
      &lt;param name="allowscriptaccess" value="always"&gt;&lt;/param&gt;
      &lt;param name="wmode" value="transparent"&gt;&lt;/param&gt;
      &lt;param name="movie" value="http://www.youtube.com/v/pIxVoDNbujM?ft=18"&gt;&lt;/param&gt;
  &lt;/object&gt;
  </code></pre>
  
  <p>(to keep it W3 HTML valid, flickering happens with normal embed code as well).</p>
  
  <p>You can see it 'in action' here:

  <p>Edit: OMG, it works properly when I'm logged out... Now nothing is clear to me as CSS is the same for users and guests, there are just few minor differences in markup...</p>
