Excellent!

The $50,000,000 question.  Well, the $3 one anyway.  :-)  I will try
to summarize here.  Maybe I can turn this into a README some day soon.

All good questions.

First thing you need is some XMLTV data.  You need to grab the xmltv
project from http://sourceforge.net/projects/xmltv/.  I would suggest
grabbing the cvs version as it's quite stable.  Once you have xmltv
built, installed and configured, grab some listings.  I cheat a bit
and run xmltv from it's build dir, but you should probably just "make
intall" it and use it as directected.  I grab 14 days worth of data
with:

$ mv /tmp/tv_data.xml.gz /tmp/tv_data.old.xml.gz; (cd /usr/src/xmltv; perl =
-I blib/lib blib/script/tv_grab_na --days 14) | gzip -9 >/tmp/tv_data.xml.gz

Which, if you "make install" xmltv properly should translate to:

$ mv /tmp/tv_data.xml.gz /tmp/tv_data.old.xml.gz; tv_grab_na --days 14 | gz=
ip -9 >/tmp/tv_data.xml.gz

That will give you 14 days worth of programming in
/tmp/tv_data.xml.gz.

Next thing to do is make up a file of programs you want to schedule.
The file is /tmp/wanted_programs.xml.gz and has the following format:

<?xml version=3D"1.0" encoding=3D"ISO-8859-1" standalone=3D"yes"?>
<!DOCTYPE my_programs SYSTEM "xmltv.dtd">

<program>
  <item title=3D"ER">
    <score>60</score>
  </item>
  <item title=3D"CSI: Crime Scene Investigation">
  </item>
  <item title=3D"Frasier">
    <score>60</score>
  </item>
  <item title=3D"The Practice">
  </item>
  <item title=3D"The West Wing">
  </item>
</program>

Put in as many programs as you wish to schedule.  Look in
/tmp/tv_data.xml.gz for program titles.

At this point, you should be able to run schedule with:

$ .../path/to/schedule

You will get some debug but at the end you will see a bunch of
commands that you can enter at a shell prompt to schedule programs.
For example:

$ /usr/src/openpvr/schedule

First thing to notice is the "Conflicts:".  These are the programs
that are running in the same over overlapping timeslot as another
program in which case neither could be rescheduled to deal with the
conflict.  If you have these frequently, you need to either:
a) watch the program listed in the Conflicts: section when it is
   showing
b) videotape it (yuck, our goal is to obsolete video tape)
c) get a second (or third) tuner card in your PVR (assuming you have
   the disk and/or CPU to record more than one program at once) and
   enhance schedule to know how to schedule multiple devices rather
   than the single that it understands currently
d) miss the conflict and get it next time 'round (assuming it will be
   repeated)

Second thing to notice is the shell commands to actually schedule the
programming.  Each group starts with an "at ..." and ends with some
".../seenput" commands.  The "at" commands schedules at jobs to do the
recordings.  The seenput commands right after the at command updates
the seen database to let "schedule" know that it's been scheduled so
that a subsequent run of "schedule" will not try to reschedule the
program or try to schedule the timeslot.

I typically only run the at/seenput commands for the next 24 hours on
the belief that the xmltv programming schedule might change to resolve
some conflicts that are happening tomorrow, the next day and so forth.

You might want to "preload" your seen database so that you don't get
(say) the last 7 years worth of Friends episodes in syndication.  I
find the following website very handy for that: http://epguides.com/
although I don't yet have a tool to automate it.  You can populate the
seen database with previously seen programs with:

$ .../seenput "<title>" "<sub-title>"

Give that a whirl and let me know how it goes.  It is likely I forgot
something so let me know if you get stuck anywhere.
