One improvement, pls. Ummy could write metadata into videofile - original download address, also user (account) address. This is to secure knowing who made downloaded video and in where it is to be found in future. I always copy this info to file and it takes time. If youtube deletes video, you will know the uploader to find cause/replacement for loss (and not see see a stupid "this video is unavailable" sign). Searching youtube by a filename is useless. Try finding "Vidéo" and it won't work. It's there, but where!
