Unfortunately, I had to “fix” this problem by completely abandoning the Plex ecosystem. For me, this is a dealbreaker. Emby, which is a much less mature platform, is handling multiple EPG per tuner with such ease, that Plex should be embarrassed. There is a “feature request” for this with 224 votes currently, that’s over 18 months old now: Multiple epg sources, for those with multiple tuners
If Plex hadn’t fixed something that simple in 18 months, I’m not sure if they’ll fix it at all.
