The operation is m. E. somewhat illogical. Tap once could z. B. watch video's for Download touch then longer business as usual. Videos that are no longer available are not automatically removed from "Downloaded", you must delete each one individually. It lacks a function to mark and then "Delete all" or "Delete selected". What I miss most are two things: - A function like "Show in Youtube" and - The display of the Youtube URL, in order to copy in "Details" Unfortunately shows "details" not at that HD versions are available, ie 720p or 1080p. So what invites "Download as video" because now down? In addition, the star rating is a mystery - what orientated which? Because, somehow, almost all video 5 stars. Menus, and so German, the overlay with the selection for advertisements or Download then English.
