Plex DVR, Trying to watch Live TV but get error "Unable to tune channel (no parts)"

hi @sa2000,
just stumbled across this thread after beating my head against the wall for last 2 weeks. @murrayd222 and @kd6icz are definitely not the only one with the issue, am on HD HomeRun Connect tuner as well and seeing the same liveTV tuning issues. Currently on 1.13.8.5395, 5388 didn’t work either.
Will send you logs later if you still need some additional references.
