You can try searching for free Usenet services, but you'll probably find that they have missing parts of longer videos like these, & not very long retention.
You can get a basic account with a good service like Easynews or Giganews for approximately what you'd pay monthly for a file locker account (Hotfile, etc), or you can try signing up for a free trial 30-day account with one of them. That way, you'll at least have a month to download as many videos as you can.
Info for finding my stuff on Usenet appears earlier in this thread, or you can use the attached nzb file for each of the movies here.
I've been posting these videos to Usenet for a long time, & there are currently 143 posts of this kind of video; if you like them, it's definitely worth checking out.
