- Download youtube-dl for your operating system (Windows, Linux, MacOS) from this link.
- You should have enough hard disk space available. Dave has uploaded 1'112'866 seconds of video footage
to his main Youtube channel. My archive of his videos is 68GB in 360p. This does not include EEVBlog2 or Altzone - You should be familiar with command line tools
. The syntax is as follow:
To download with highest available quality:
youtube-dl --continue --format best https://www.youtube.com/user/EEVblog
or to download in 360p to save hard disk space:
youtube-dl --continue --format 18 https://www.youtube.com/user/EEVblog
Once you downloaded all videos, you will require 12 continues days/24 hours a day to watch all of them to catch-up

. Or watch in 2x,3x...32x.
If you want to save his comments for each video, add
--write-description to the command.
After downloading, if you ever watch any of his videos and liked it, do not forget to open it directly in Youtube to hit the Thumbs-up

P.S.: It is possible to download Dave's playlists, videos after/before specific dates or many other different options. Please refer to youtube-dl manual for more information.
