OK, looks like I'm cooking with gas now! Thanks, btw, for your help
pointing me in the right direction. I rewrote the grabber script in perl
to simplify things and, quite frankly, because it looks neater (to me).
Below is what I have done on my system. Mind you, this is setup for a
single lineup. It's a relatively minor change in the scripts to be able
to iterate over a list of lineups, if one needs to add that.
1) Ran /usr/bin/tv_grab_na_dd --configure
2) Changed the mythfilldatabase command in the MythTV settings (on my
system, it's under General settings, mythfilldatabase Program in the
setup on the frontend) to /usr/bin/my_grab.pl (see below for that script).
3) Added a cron job for /usr/bin/my_mythfilldatabase.sh (also see below
for script) to run at a time of my choosing, 4 a.m. (I.e., ran crontab
-e as mythtv and added the line "0 4 * * *
/usr/bin/my_mythfilldatabase.sh" without the quotes, of course)
4) Started enjoying my new life without worrying about mythfilldatabase
bogging things down at inopportune times!
I sincerely hope this will help anyone else who may be in my shoes.
