I have warning that an incorrect mime type was detected
Your web server is not reporting file types correctly. This may cause problems with certain podcatchers, namely iTunes. If you're familiar with editing the .htaccess file, look up the correct the mime type for the file type, and add the correction to your .htaccess file in this format:
In addition, verify you are entering in your file URL correctly. Copy the URL into a browser and make sure the link you are giving Podcasting plays in the browser. Common mistakes include have /public_html/ in your URL or not linking to the full URL (using a relative URL like /download/file.mp3).
