Feels very redditty, which is why I'm asking...
Also, what are total buffer size (what does it affect) and session waste (what does it affect)? qbittorrent-nox on Linux.
How: lots of storage, good networking infrastructure, patience
What: anything that was originally recorded on and not just upscaled to 4K
Time: my current repertoire of 127 torrents I built in five-six years
