Had a curious thing happen at a client's meeting.
Compressed all of the videos using H.264 and used the HTML5 with MediaElemment.js playback feature of the plug-in. The videos played back great under IE6,7 and 9. Firefox, Chrome and Safari. The iPads and iPhones all worked too. But in IE8 the video would not show, we can only hear the audio. Very strange.
Anyone else had this experience? Is there something we can do to get them to work? I would not think it is the MP4 files since is works in other versions of IE.
