myTV (formally tvtrss) is a script that will scrape your favorites RSS feed from tvtorrents.com or showRSS and submit new links to transmission-daemon. It includes regex filters, auto-expiration of torrents based on seed ratio, destination directories for completed torrents, Twitter notification of completed torrents, and RSS history.
TorrentWatch-X is a Web-based tool to automate BitTorrent downloads. This is a fork of the torrentwatch project, now also with NMT support. It is meant to run on Linux and Mac OS X with different BitTorrent clients (for now, only Transmission is supported directly) and make it work in all Web browsers. It supports RSS feeds from a few torrent sites that offer TV shows. It can save torrent files in any folder, so any torrent client can pick it up. It can tell Transmission to save data in any folder. It can tell Transmission to stop when a certain ratio is reached. Authentication with Transmission is supported. Your own RSS feed can be added.
pytvshows downloads torrents for TV shows from RSS feeds provided by ezrss.it (previously tvRSS.net). It is designed to be run from cron or a shell and interfaces with BitTorrent clients like Transmission (via the Transmission RPC API) or any other BitTorrent client that supports folder monitoring (most). This is a resurrection of the venerable pytvshows script by Ben Firshman.
