The system works quite different from torrents however for the user, wants it's setup the process for downloading shows/movies is quite similar. First you'd want to start by downloading the free software SABNZBD which would work similar to Utorrent, it processes the downloads. Then you need an indexer which costs around $15 a year works as your search engine. You'll also have to pay for a newsgroup provider, I recommend newshosting.com that runs around $12 a year. There are plenty of youtube videos that can run you through the setup process. With NZB files you're not an uploader, therefore you don't get hassled by your ISP like we see today with torrents. Also with this system it downloads to the full capacity of you internet connection. I have gigabit service so I download full 4k movies in about 12-15minutes.
