Video not appearing in Internet Explorer 9
Since the only threads I could find on this seem to be quite old I thought it might be worth starting a new one.
I've recently updated some JW Player videos on our site, and they seem to be working well in Firefox,Chrome, and I.E 7 and 8. However in I.E 9 the video doesn't seem to work (the video does not appear, and a 'slow running script' freezes the browser) and in I.E 10 and 11 I get an 'Error loading media: file could not be played' message.
I have ensured that the page is started with <!DOCTYPE html>, and that the video MIME type is served up as Video/MP4. Is there any other problem or error in coding that could be causing this issue?
An example page which is affected is:
