Free video downloads

I know the videos are available on YouTube. However, I'd like the ability to download all videos (like on the Biz package). Is that possible?
I live in a remote area and use HugesNet Satellite for Internet access. It is expensive and slow. But mostly, it is very restrictive to 50 GB of download or less a month before being slowed to barely browsing speed. So I like the idea of downloading video files from your site (or another one you select) so I may watch them over and over should I find problems learning with the controls.
Thanks for considering this for us who live away from fast cable/Wi-Fi and are slow to learn. :-)
