Youtube + Emacs

Morning,

For my sins i am interested in learning Emacs Org Mode. I’m often without internet access.
Is there a good way that someone know how to download YouTube instructional videos for later playback?

Use youtube-dl. It’s already installed in NomadBSD, and can be used to download videos from all sorts of sites:

% youtube-dl 'some-youtube-url'

Works great thanks.
