The media player begins loading the video file but does not appear to finish so the video could be played. The error occurs when using the IE7 browser under Windows 7. The player works as expected for IE8/IE9, Chrome, Firefox, and Safari (on all device types PC, iPhone and iPad).
It appears that everything is being defined correctly if you look at the generated code. It does seem that the player is not getting the indicator that video is ready to be played.
