I accidentally found thes "Universal Media Server " ( UMS ) in the Web , which is available for Linux too.
Then I searched the forum and found the old thread. Just built my first OMV - looking to add UMS/PS3MS

I have not yet any experience with a mediaserver but the spec's of UMS seems to better than PLEX ?
In the future I'll also use a media server with my smart tv.
What do the experts think about this UMS . Will there be eventually a plugin for OMV ?
