Google Chrome version (10.0.648.127): Operating System: Windows 7

Adding the HTML5 <video> tag appears to cause rendering issues with jQuery slideDown() method. I have tried jQuery version 1.4.2 and 1.5.1 and each has the same issue.

The problem can be seen at this URL http://dev.tribeuk.co.uk/portfolio/project-one/. The slide should work as it does here - http://dev.tribeuk.co.uk/portfolio/ and removing the <video> tag does make it work correctly.

It works correctly in every other browser. I am fairly sure it worked properly in Chrome previously and I have only noticed the problem today.
