upload video to media in umbraco v 6.1

I am running umbraco 6.1 and trying to upload a video to a folder in Media. I set my values in web.config for maxRequestLength and maxAllowedContentLength well above the size of my video. I set them to 250000, and the video is only about 100MB. When I attempt to upload the file, it appears as if everything is working as expected, but the video file is not in the media folder after the progress bar finishes. I also made sure in iis7 I had an entry for my file type in MIME types.
