After an initial hiccup, I was able to figure out this add-on. It worked as advertised. The first video dl'd without a hitch. The one thing I can't figure out is, some videos produce a really long list of GET requests. I was told that the first m3u8.ts in the list corresponded to the video I was after, but it didn't. I gave up after a while. No big deal really. It still beats FreeMake downloader, which cost me $60 and fails more often than it works.
