I prefer scene releases as there’s a decent quality version in whatever resolution for practically everything - and being properly tagged you can usually find the exact file on places like Usenet/IRC. One trick I use is to search in BiglyBT for the exact file size in bytes as per srrdb, and it often comes up with something (sometimes even several torrents with no seeds that can be swarm merged).

Not quite. It let’s you seed two or more different torrents that have the same (bit-identical) media file, and automatically merges and cross-shares the chunks between them. Even if there’s no seeders on each individual torrent, it’s feasible to combine the downloading power to get them completed and become the seeder. Done it many times and works pretty well.
