jPlayer doesn’t play in IE9
Using jPlayer to play video works fine in Chrome and Firefox and the iPhone, but does not play in Internet Explorer 9 (IE9). In IE9 it just shows a black screen and goes back to the first frame.
What seemed to fix the problem was defining the mime types. Simply add the following lines to your htaccess if you are trying to play mp4 files:
AddType video/mp4 mp4
AddType video/mp4 m4v
