How do you use clipgrab to download Late Late Show Craig Ferguson?

[9Benua]

Hi guys, I just downloaded clipgrab. I want to use it to download Craig Ferguson streaming video. http://www.cbs.com/shows/late_late_show/video/A4B3F9A6-EDA3-7B25-C26F-AEF4B2BAFCA8/the-late-late-show-3-27-2013/

I put the link into the download tab of clip grab, yet, instead of downloading the streaming video, I got this error message instead: No downloadable video could be found.

Did I do anything wrong? What program should I use to download that streaming video?

Clipgrab only supports a few video sites.

Have you tried the firefox plugin to download videos?
