Playlist not a valid XML file in IE only..

I have a playlist and it works fine in FF. I don't use IE but opened the site to check something the other day and see the videos don't work and just have a message in the black player box that says:

This playlist is not a valid XML file.

Here is the playlist.xml file. Could someone tell me what is wrong.
As I said, it works fine in FF 9.01 but not in IE 8.
