=head1 NAME
tv_grab_dtv_la - Grab TV listings for Direct TV Latin America
=head1 SYNOPSIS
tv_grab_dtv_la --help
tv_grab_dtv_la [--config-file FILE] --configure [--gui OPTION]
tv_grab_dtv_la [--config-file FILE] [--output FILE] [--days N]
[--offset N] [--min-delay N] [--max-delay N] [--quiet]
tv_grab_dtv_la --list-channels --loc [ar | cb | cl | co | ec | pe | pr | uy | ve]
tv_grab_dtv_la --capabilities
tv_grab_dtv_la --version
=head1 DESCRIPTION
Output TV listings for Direct TV channels available in Latin America.
Listings for the following countries are currently available:
Argentina, Caribbean ('cb'), Chile, Colombia, Ecuador,
Peru, Puerto Rico, Trinidad, Uruguay, Venezuela.
The TV listings come from http://directstage.directvla.com/
The grabber relies on parsing HTML so it might stop working at any time.
First run B<tv_grab_dtv_la --configure> to choose, first of all your country
and then which channels you want to download. Then running B<tv_grab_dtv_la>
with no arguments will output listings in XML format to standard output.
The grabber doesn't generate stop times, so you may want to run
tv_sort on the output to generate them.
B<--configure> Prompt for which channels, and write the configuration file.
B<--config-file FILE> Set the name of the configuration file, the
default is B<~/.xmltv/tv_grab_dtv_la.conf>. This is the file written by
B<--configure> and read when grabbing.
B<--gui OPTION> Use this option to enable a graphical interface to be used.
OPTION may be 'Tk', or left blank for the best available choice.
Additional allowed values of OPTION are 'Term' for normal terminal output
(default) and 'TermNoProgressBar' to disable the use of XMLTV::ProgressBar.
B<--output FILE> Write to FILE rather than standard output.
B<--days N> Grab N days. The default is 3.
B<--offset N> Start N days in the future. The default is to start
from today.
B<--min-delay N> You must insert a delay between page requests to avoid
unnecessary load on the website. If you try to grab pages too quickly then
it's likely you will get banned by the website providers (and may get
all other xmltv users banned as well!).
Suggested value: 1 (seconds)
B<--max-delay N> Maximum delay between web page fetches.
Suggested value: 3 (seconds)
B<--quiet> Suppress the progress messages normally written to standard
error.
B<--capabilities> Show which capabilities the grabber supports. For more
information, see L<http://wiki.xmltv.org/index.php/XmltvCapabilities>
B<--version> Show the version of the grabber.
B<--help> Print a help message and exit.

L<xmltv(5)>, L<tv_grab_ar>.
=head1 AUTHOR
Most of the grabber was made by Lic. Christian A. Rodriguez <car@cespi.unlp.edu.ar>, with a
lot of help from others, specially Joaquin Salvarredy <jsalvarredy@cespi.unlp.edu.ar> who
tested the grabber from its early versions and Lic. Nicolas Macia <nmacia@cespi.unlp.edu.ar>
=head1 BUGS
This grabber extracts all information from Direct TV Latin America website. Any change in this
web page may cause this grabber to stop working.
