I use youtube-dl to download whatever I want - it's a leeeetle bit slow, but really not a problem. It's a command-line tool so takes some getting used to if you're not familiar with that, but it's not complicated (I can give you some pointers via pm if you like) - check it out: https://youtube-dl.org/ Best feature is you can pass it a text file of video URLs and it will download all of them in the background
