Got this from a previous SOS offer, last July. Have only used it a few times, but recall that it worked rather well for those occasions. There are a number of these downloader programs around, some being free and others like this one, Applian Replay, Jaksta, or Tubedigger being normally for pay. There are also some in the form of browser add-ons. What I’ve found is that it is advantageous to have several of them in your toolbox, as some will work for certain sites and downloads but not for others. I really doubt there is any one that handles everything.
