In order for this to work you need ffmpeg. I tried with version 1.2.1.

1) Play the video you want to download in the browser
2) Inspect the video element on the page
3) Copy the video url from the page source (something like http://devstreaming.apple.com/videos/wwdc/2013/.../101/ref.mov)
4) In this url replace "ref.mov" with "iphone_c.m3u8" (for 960x540 resolution) or "atp.m3u8" if you want more (probably 720p?)
5) Execute `ffmpeg -y -i http://devstreaming.apple.com/videos/wwdc/2013/.../101/iphone_c.m3u8 output.mp4`
6) There is your video :)
