Podcast Submitted to iTunes Was Rejected After Using iLife '09

So, I created a podcast using Garage Band '09 and iWeb '09 and submitted the feed to iTunes directly from iWeb. One week later I receive an email "iTunes Store Podcast Rejected Notification" notifying me that the removed my podcast and to troubleshoot my feed and re-submit. I figure since I used Apple products to create the podcast that the feed would have complied with all feed requirements. Also, since the XML is automatically generated through iWeb, how do I troubleshoot the feed manually. Anyone have any ideas?
