 When a user uploads an mp4 file, it will not play in Safari.

 We have determined that this is not an issue with our Apache server (seems
 to happen to some folks that they have disabled range request headers) as
 the same file uploaded elsewhere on our server but externally from the
 wordpress site loads fine.

 It seems that perhaps the video is attempting to load in byte ranges but
 that Wordpress is returning a 200 response instead of a 206, but that is
 just a hunch.
