content: I recommend using "youtube-dl" on any channel you're interested in. It downloads every single Youtube video on a channel (if you feed it a playlist link with them on it) or any collection of youtube videos. You can set the resolution, audio for optimal quality. I use it to download thousands of youtube videos at a time. To get used to it, install it and then open a terminal and type "youtube-dl URL" with youtube-dl -F URL giving you a list of quality options and youtube-dl -f (number selection) URL allowing you to download in that format.
