I know that there have been a couple of films/clips floating around on various sites.
I think that irongeek has even done a couple of video tutorials www.irongeek.com

One of my favorites is warriors of the net. http://www.warriorsofthe.net/

Oh yeah... can't forget thebroken... http://www.thebroken.org/index.php

I also listen to the off the hook archives, which are *sometimes* worth it.

Is anyone aware of other interesting clips regarding security/networking/computing/etc?

I have techtv and only get to watch it when I'm at the gfs house and she is not there... she hates that channel. anyway...

Sometimes I like to watch the video rather than always reading books or sites or texts....
