I'm looking to be able to capture videos that are streamed in RTMP
format, and there's a tool called rtmpdump (and associates) in the
Ubuntu repositories.  However, it doe snot appear to work properly:

$ grabit
Reload the video page, start the video and watch for the rtmp information
When the video information appears, type ^C to halt the rtmp server.

Instead of the download, I get this:
