The MythTV wiki (https://www.mythtv.org/wiki/Mythfilldatabase#Channels) says it should:
... but it doesn't. After enabling a couple extra channels in SchedulesDirect.DB, I've re-run mythfilldatabase with no arguments and even tried adding --do-channel-updates even though the wiki says this option only applies to the old DD grabber. Either way, the channels don't get added to the MythTV database, and as far as I can tell, there are no errors or warnings in the output to indicate why.By default, mythfilldatabase will add or update channels that are included in the input file if the tuner type supports it. That is any tuner that does not scan for channels....
Is the wiki correct -- is mythfilldatabase supposed to add and update MythTV's channels from the XMLTV grabber (tv_grab_zz_sdjson_sqlite), and if so, how do I get it to do that?
Edit: I have two lineups -- one for cable, and OTA. In SchedulesDirect.DB, I enabled one new channel in each lineup. mythfilldatabase does not add either one to the database.
