Sometimes the presenter will have some setup or just mention a config and if you aren't on the exact same version of IDE/editor then everything looks different and you're lost. Then there is the larger problem of older videos are 100% irrelevant if the stack of tech they use has had recent updates. Maybe this is more game programming related because major version changes will have menus moving around or new/different options. I would imagine a new person to web development would feel the same if videos were on IDE version 1 and that IDE is on version 3 now (replace IDE with editor or whatever you use).
When I tinker with something new and there is a written setup guide, its much easier to follow along. I almost think video streams aren't the right format for learning.
