If you've assigned a Media RSS file (from Flickr, for example) as a flashvar in your player embed code, you will need to wrap the xmlFilePath value with the Javascript escape() method because of characters like ampersand that may cause variable parsing errors. For example:
xmlFilePath: escape("http://api.flickr.com/services/feeds/photos_public.gne?id=99501315@N00&lang=en-us&format=rss_200"),
xmlFileType: "Media RSS"
