How do you you capture (record) the stream from NBC Olympics website

[BusterAvis]

NBC Olympics has their "Live Extra" streaming of the 2012 Olympics.
Every single event is streamed live, and then archived on demand to watch on their website. The website is: www.NBCOlympics.com.

I can't seem to record the stream.
I have tried Replay Media Catcher.
I am not interested in doing a "screen capture" from my desktop.
I want to capture, I mean catch and record the streaming link.
Normally Replay Media Catcher can record anything from Youtube.

NBCOlympics.com is indeed using the Youtube platform for their streaming. However, it's not working like it usually does on Youtube.com. It won't detect the stream at all. You can watch 720p or even 1080p of these events on the NBC Olympics website. I want to be able to record some of it. Please help. Nothing is working. And again, I'm not interested in a desktop screen capture program. I want to record the actual stream, without having to use any desktop screen capture programs. Normally, Replay Media Catcher is supposed to work. Any other suggestions?
