I'm getting this:
html5.js not found in your template! Videos might not play in old browsers, like Internet Explorer 6-8. Get it here and put it into your template.
jQuery library http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js is old version and might not be compatible with Flowplayer.
I checked https://code.google.com/p/html5shim/ and I'm not sure what to do with the zip file.
