I've recently bought a new external HDD, which I was planning on having all my movies/shows in, and plugged into the TV. It works just fine, but sucks having to go to USB - Folder - Folder, etc, and doesn't have the funcionality of Plex for example where you can download subtitles and correct them with timing. Another amazing thing it does, is showing which episodes you've watched, or part of the movie that you've already watched.
Is there any such local media player, that can fetch USB connected media? I'm aware I can just use plex and have that HDD plugged into PC, but the downside is not being able to watch anything if the PC is turned off. The subtitles is specially important to me, to be able to either download them or correct them.
