Use a video downloader, if one server won't allow download pick another. Torch browser has a built in "media grabber" that will download the videos. There are also many other "fmovies" websites, just do a search for fmovies
A tip, these fmovie websites are popup spammy, something uBlock works well to greatly reduce the popups.
