ProPlayer Source URL is Breaking

Check out my use of ProPlayer on this page.

The player is embedding fine. However, when you click to play the video it’s reporting the source URL is broken, as:

Video not found:
http://www.foodmayhem.com/uploads/2008/04/gordon

However, if you examine the XML file for ProPlayer it has the correct source URL:
http://www.foodmayhem.com/uploads/2008/04/gordon_ramsay_perfect_scrambled_eggs.avi

How can I fix this?

Thanks,

Lon
