Need help downloading a video, I have tried many options

[Inishi]

Hi, I'm a college student, and I need to have access to some videos offline. They are for financial education for rural and vulnerable populations. The videos are free, but you need internet access to view them, which does not help when you have to go into a zone without good cellphone reception and no internet. I tried using flashgot, jaksta, getflv and streamtransport. Then I tried using urlsnooper, but while it does react to youtube videos, it doesn't give me an address for this site.
This is one of the pages that has an FLV JW player

When I look at it's source, the only .flv file I find is

http://www.finanzasparatodos.org.mx/...fb56a9 89.flv

Which isn't helping.
Any tips as to which software to use, or tips to understanding how to get a file address to download the videos?

Thanks in advance!
