A few months ago I grabbed this torrent from rarbg, and it took weeks to download. Often going days with no seeders.
I finally got it, and decided I’d seed beyond my usual 2x to help others get this. Then rarbg went under, and now I think I’ll just keep this one going.
Unless it was something really obscure I never had problems finding seeders.
I use the search engine function inside qBitTorrent and I sort the results descending by the number of seeders. To enable it go to View > Search Engine (iirc) and follow these simple instructions.
qBitTorrent also has a feature that lets you download a torrent in order of their pieces, and also download the first and last piece first, which is basically streaming. No need to wait for the download to finish first.
If needed, VLC has a built-in plugin called VLsub which lets you find and automatically load subtitles for almost anything. To enable it go to View > VLSub.
qBitTorrent + VLC is my Netflix. Never asked me a cent, but to me they are priceless and more convenient than any subscription service.
On Android I use LibreTorrent + VLC.
