I am having an issue with an MP4 video in IE. I am getting a "MEDIA12899: AUDIO/VIDEO: Unknown MIME type:" error in IE. I am thinking it is an issue with either server that is hosting the file or the mp4 that was supplied to me. works fine in Chrome, Safari, and Firefox. In IE 9, I am getting a more defined error... "Unable to get property 'pow' of undefined or null reference"

```
    <source src="http://dummyurl.com/video.mp4" type="video/mp4" />
    <source src="http://dummyurl.com/video.webm" type="video/webm" />
    <source src="http://dummyurl.com/video.ogv" type="video/ogg" />

```

any thoughts or ideas on this?
