FWIW: The link to the channel 9 site is https. I tried in Firefox and IE. When the page loads you get one of those mixed security messages. I wasn't able to get the video to play regardless of what my choice was in the security prompt, I get a Media Failure message in the video player.

However, if you access via http (no s), then the video does play fine, so perhaps the link in the post can be updated.
