Well, taking a quick look at things, what it looks like is happening is that you're probably feeding iTunes the wrong url. What is happening at Feed Validator is that it it going to
http://kitesites.libsyn.com/ and seeing that you have an RSS feed for that page, and it then reads the rss feed, which is at the URL
http://kitesites.libsyn.com/rss . iTunes isn't doing that - it's just going to the URL you specified, and it sees that URL isn't a proper XML file - it's an HTML file instead, so it can't pass validation. What you need to do when submitting your feed to iTunes is you need to give it the URL of the RSS feed, not the URL of the HTML page. If you try submitting the url
http://kitesites.libsyn.com/rss then it should validate.
