howto download fcgov.com pegcentral videos with rtmpdump

[fcvideos]

http://www.fcgov.com/cable14/video-archive.php

A few months ago fcgov.com changed to pegcentral format. I have not been able to figure out how to download. From reading various posting here and elsewhere, looks like rtmpdump should work (Umbuntu 13.10). However, I have never used rtmpdump before and I cannot figure out the command line.

I want to be able to download anyvideo from the above site, but this is the one I tried in the tests below.

Thank you.
