Linux Equivalent To Techsmith's Camtasia?

I need to make a video presentation on how to install, setup and use VPN on mandriva.

here's the the link to camtasia's site for those who dont know about it
http://www.techsmith.com/camtasia.asp

TIA.

Not as fancy, but you might look at:

http://sourceforge.net/projects/xvidcap/

http://live.gnome.org/Istanbul

http://recordmydesktop.iovar.org/about.php

I don't know how to do it :( but it should be possible to run Mandriva in a VM environment and use Camtasia to record the VM?

EDIT:

Sorry, had to go fire up my Ubuntu box.................. there are a whole load here:
