I would imagine they mean something like jellyfin/plex, which don’t necessarily get you away from torrents. Unless you want to go the slightly more legal route of ripping DVDs and Blu-rays and re-encoding everything for yourself. I say “slightly more legal” because while you are legally allowed a backup or archival copy of your own media (in the US), you still usually have to violate the DMCA to break encryption so you can rip your archival copy.
