Stream capture from NBCOlympics

[nwtim]

Back in 2012, I got a number of extremely high quality videos of the London 2012 Olympics from the NBCOlympics site using ffmpeg to input the stream from a URL I got from Firefox's Web Console using the .m3u8 filter. In trying to do something similar this year for the Winter Olympics, I'm able to play the videos in Firefox, but I've had no luck coming up with a URL to try to grab.

Instead, the best I'd probably be able to do would be to get the 5-second long snippets that tick by and merge them together.

Is anybody successfully doing this or can help me find the URL that addresses the whole video stream?

Thanks!
