Every current television show is available on BitTorrent and most of the
.torrent's are syndicated via RSS-feeds. TVShows was a great application that hid all the RSS stuff and allowed easy show subscription with some mouse clicks.
Regrettably it doesn't function any longer,
as it is blocked by its feeder website.
I wrote an easy tutorial that describes how to restore that functionality with some freely available tools. This article is written for users of OS X Leopard, but it should apply to Linux as well. Read it over at TorrentFreak.com.
PS: In the past this tutorial was hosted here and as a slightly modified version over at TorrentFreak. I think it's a good idea to remove the tutorial from here and just point to torrentfreak.com, so that additional comments, questions and tips pool up in a single place.
