The embedded commercial player uses the license key for flowplayer.org, the domain from which it is loaded.
Important note: Internet Explorer 9 throws an error when encountering a Flash object in IE9 mode. You can avoid this by adding the following as first meta attribute in the head section of your page:
<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE8">
Or you can achieve the above more globally on the server side, for instance in a .htaccess file:
BrowserMatch MSIE best-standards-support Header set X-UA-Compatible IE=8 env=best-standards-support
