Thanks Maksim. By WMC do you mean Windows Media Centre? This is a Linux server with Kodi and doesn’t really bear much in common with a Windows setup.

I don’t do live TV actually, all the content I consume is internet-based these days. With the addition of a TV tuner you could certainly do it – MythTV as the backend with the Kodi PVR plugin would probably be the way to go.

edit: I see what you mean now! Yeah the Windows Guide is a great service. I haven’t used the open source equivalents, but the MythTV community would be a good place to start: https://www.mythtv.org/wiki/Electronic_Program_Guide
