# This script uses http://ezrss.it to check for the lastest episodes of your
# favorite tv shows, which you'll have listed in the "followed-shows" file.
# Run mypvr.sh from your chosen directory. First, the above list file will be
# set up, once this is done the script can be controlled via a crontab or on
# PC startup, or both. Here's a crontab to check for new shows every 2 hours.

# Selected .torrent trackers will be sent to your "Downloads" directory ready
# to be picked up by "Transmission" gui/daemon or any other client that can be
# set to auto-load from a monitored directory.
