You're not using Plex on OS X because you're not familiar with OS X so you're going to wait for something 'better' to use on-OS X? You're correct, Plex is the best, and there have been a lot that have come (and gone) claiming to be better. So far none have even been able to duplicate it. Not that it couldn't happen, it might but why wait for a possibility when the solution is there. sub title requirements is a major % of the Plex user audience. There are many many plugins and automated services that help with this. You should read the forums on subtitles as there's a ton of info on the subject. You can also start off by installing a subtitle plugin channel on pms. You can also install Plex on windows if that helps.
