[mythtv-users] Rescanned OTA channels and Lost most of them

[John]

I had the similar issue with EIT data after a full rescan(for that 
source), where one transponder had changed frequency. I could tune to 
the channels on the mux and use the previously received EIT data for 
those channels to schedule but no new data was received. Note I have two 
input sources SAT and Terrestrial. I only cleared the Terrestrial before 
doing a full scan for that source. EIT was still being received for the 
other source.
A complete deletion of all channels on both sources and a full rescan 
fixed it.
