I down load a lot of youtube videos. I don't always keep them because after all they take up room, and most of the time once you've viewed them once It's enough. However I like doing it this way. I can put them on a flash drive and watch them at my convince, when my mind is fresh, and no distractions like you get when your on the youtube website... Distractions would include advertisements, other recommended videos, and not to mention your own emails popping up with various forum posts bagging you to go check things out. Another reason why I like to down load youtube videos is sometimes all that's in them is audio. A good example would be Spatry's Zoo Crew. It's much easier for me to load them onto a mp3 player and listen while I'm doing my job (Cleaning the school)
To solve these issues:
In windows I use format factory.
What do we use in Linux?
