Hi there

For anybody messing around with Media server I recommend they look at PLEX these days --FREE, subtitle problems all seem fixed and great quality. Mezzmo (Paid for software) only works on Windows and a few movies I have hangs the whole system when I enable subtitles.

PLEX also works great on LINUX servers and casting to a Google chromecast device turns even an old TV into a smart TV,

Note you do need to have an HDMI connection though on the TV.

Shows how Free and Open source software is still viable these days - you don't always have to pay through the nose for decent software.
