how many days for mythfilldatabase?

Seems to me that mythfilldatabase is only grabbing 2 days (48 hours) of program
guide? Is this so? Is there a way to control this? Feel free to point out my
stupidity and tell me it's in section x.y.z! I can't find anything but a section
in the mythfilldatabase source code..

I'm not sure if this is what you mean, but my experience is that after the
initial mythfilldatabase run, the daily one will download the following
day's info and then fill in one day two weeks in advance so that the
database is always populated for the full two weeks.

If this is not what you are seeing, then you will have to give a little more
info, perhaps sample output.

It is certainly country specific. In the UK grabber, 3-4 days is all that is possible... (limitation of the site where listings are retrieved from) However, I notice that tvtv.co.uk offers 2 weeks worth of times, so perhaps a grabber can be written for that site...

Ok, that is indeed my question. And I'm not seeing what you suggest. Rather it
seems that mythfilldatabase is getting the following day only. It doesn't
indicate that its having any trouble either. Wasn't there some setting that
controlled how many days of programming it kept? Maybe it was during the build
stage? In any case, any suggestions on where to look for trouble? I was able to
use tv_grab_na to grab 7 days worth of listings (using my
$HOME/.mythtv/DirecTV.xmltv as the config file) into a file. Then I invoked
mythfilldatabase with the input file options and it happily parsed the file into
the myth database.

I think it has worked this way for a long time now:

If you run mythfilldatabase+tv_grab_na immediately after it
has just run, it only grabs program info for one day (tomorrow). If
you run it once a day, it will only grab info for two days (tomorrow
and tomorrow+7). It grabs a full 8 days worth only when your database
is empty (eg. the first time you run). On subsequent runs, it always
grabs program info for the next day (to pick up programming changes).
It will then check to see if it needs to grab program info for today
and for the next eight days. If any programming info for that day
already exists (at least 20 programs in the table), it will not grab
program info again.

Aha! Now this mystery is solved. I didn't mention that I'm also running
the ppv.pl script that Nathan put together. This fills the ppv info for
DirecTV out at least 1 week into the future and it's plenty more than 20
channels worth. So I have a little more work to do after I do my ppv updates.
