That's the way I used to do it, before I flailed around off and on for a
few months and got xmltv to (mostly anyway) work with the JSON service. It
was after I switched to SD JSON that the automatic mfdb that myth runs
daily(?) stopped getting programming updates. I found that
mythfilldatabase --only-update-channels *does* update the schedules, but it
takes 15-25 minutes to complete, so I figured there was something
sub-optimal about my config, which is why I started this thread.

Ah, that's very helpful to know.

I think you meant "likely" :-). I've successfully made small edits to the
db before, and the temptation to use the where clause is great enough that
I will try again! (Will backup entire system and database first.) Thanks
for that tip.

Thanks Geoff, this is very helpful!
