[mythtv-users] Getting schedules direct guide data for a new channel

[Tom Dexter]

I mentioned this in another thread regarding channel scanning, but I'm
sending this separately, as I'm having no luck here.

I rescanned an ATSC transport (New York 11) and picked up a new
channel 11.3 on that multiplex.  I can tune the channel in no problem.

I've enabled that channel in my lineup on schedulesdirect.org.  I know
that schedules direct has data for that channel as I can see it for my
area on zap2it.com, yet when I run "mythfilldatabase --dd-grab-all" I
get no data for that channel.

What piece am I missing there?  Do I have to use mythfilldatabase with
the "--do-channel-updates" option, or fetch the channel lineup in
mythtv-setup?  Some of the stuff I'm reading about either one sounds a
bit scary.

Thanks in advance.

Tom
