[mythtv-users] Responsiveness of zap2it to lineup discrepancies?

[f-myth-users at media.mit.edu]

Oh wait a minute, apparently I'm blind---my version of
mythfilldatabase -does- have a --do_channel_updates flag.
[Why isn't this --do-channel-updates instead for consistency?
Never mind.]

Should I just run it by hand with this flag, followed optionally
by running it again with --refresh-today if today's listings aren't
fixed?  Should I take care to run it as the mythtv user and not as
me or root, or does this not matter?

Is there some reason this should be a default argument to my calls to
mythfilldatabase every day, assuming that I'm not hand-editing my
channels?  (I'm not, and have no wish to start.)  If so, I'll add
that along with --no-delete, which I've been meaning to do for ages;
I presume this is some page in the mythtv-setup UI somewhere that I
need to go hunt down again.

Thanks.
