[mythtv-users] Using XMLTV source with mythexternrecorder keeps adding additional channels

[Erik Merkle]

When I switched from Data Direct to XMLTV I had an issue where mythbackend
kept running mythfilldatabase with the "--dd-grab-all" option. It took me a
little while to figure out that option was being used because it was
configured in the datatbase as the value for MythFillDatabaseArgs. Once I
cleared that option, mythfilldatabase started running correctly for me when
spawned by mythbackend.

If you always want "--only-update-guide" to be passed to mythfilldatatbase
when run by mythbackend, you could add that value to MythFillDatabaseAgs in
the database. This could allow you to let mythbackend manage the schedule
and not have to create your own cron to run it.

I am not a myth database expert by any stretch, and I have not found a lot
on that particular setting. But you can see what value you have by logging
into your database and running:

select value,data from mythconverg.settings where value =
'MythFillDatabaseArgs';

If you have any other options in there currently, you'll want to append
"--only-update-guide". If it's blank, you can just set it:

update settings set data = '--only-update-guide' where value =
'MythFillDatabaseArgs';

Hope that helps,
Erik
