I guess Feedburner needed a good night's sleep, that's all. I say that because the Feedburner feed (
http://feeds.feedburner.com/emiratesmacpodcast) works again this morning, all four items in the podcast appear okay.
So keep subscribing to the Feedburner feed and we hope this was temporary and that it will keep working from now on.
It works for me in both iTunes 6 and 7. If you have problems, first remove the subscription and add it again.
