I replaced mythtv with tvheadend on the backend and kodi on the frontend like 5 or 6 years ago.

The setup and configuration at the time on mythtv was slanted towards old ( obsolete ) analog tuners and static setup and tvheadend was like a breath of fresh air in comparison where you could point it at a DVB mux or two and it would mostly do what you want without having to fight it.

I’m not sure how much longer I’ll want something that can tune DVB-S2 and DVB-T though. Jellyfin and friends handle everything other than legacy TV better than kodi these days.
