Recently I started torrenting my anime, as many people do. However While I would usually download .mkv files and watch them in DivX, I find that a good portion of my torrents end up having no subtitles, despite the fact that they are subbed.

Basically, I know that a lot of them are soft-subbed, but I can't see or alter anything to do with .srt files, or anything similar because I download the single torrent. I've tried plaenty of different codecs but nothing seems to work, so I'm wondering if there is a good player/codec combination that will allow me to get the subtitles working, because I'd like to continue using .mkv files because of quality.
