I only recently discovered this, too. I was complaining about how I preferred reading than watching videos, partly because I can read a lot faster than someone can narrate, and because I can "skim-read" text. They suggested playing the video back at a higher speed, and it works fine. Still haven't quite solved the "skim-read" thing - guessing where the narrator stops the "welcome to my channel, smash subscribe and like, etc" bit is tricky.
