Ok so I found this answer to someones question about how to download youtube videos via youtube-dl. It had all of the information that I needed, except how to open the video.
Here is what I have so far:
sudo apt-get update sudo apt-get install youtube-dl youtube-dl youtube-video-link
It downloads ok, I just don't know how to open it. Again, thanks for your help.
youtube-dl URL, where
URLis the URL of the video.
