Downloadable versions of video lectures

When watching the videos from the fastai course website and then using the share link it brings one to the youtube site. In NYC, we transit underground which is about 3x faster than Uber and without wireless access so I try to download files but I don’t know how to download the versions on the fastai website which is what the youtube version refer one to. How does one download the newest versions of the lectures?

Thank you in advance.

Use some kind of google chrome downloader plug in to download the videos
