So to my understanding, the Stremio + RD (Real-Debrid) + Torrentio is working in such a way that, Torrentio is the aggregator, then Real-Debrid will work as direct download for the torrent, and finally Stremio will play the content from the link. So technically speaking you don't need to deal with downloading stuff.
