I've been using OMV since one month and it's working great combined with SABnzbd + Couchpotato + Sickbeard it's a NAS + download server.
But my media players using YAMJ (Yet Another Movie Jukebox) to create nice GUI to watch movie information, but I need to run this manually from my PC to keep it up-to-date with the newest movies.
Is there anyone who has YAMJ running on OMV? I've found an script that runs automatically after adding new content.
Next week I shall give it a try, keep you updated!
