Lilx.net has a great Tv-calendar that makes it easy to check when the latest episode of your favorite TV-show is broadcasted. To make it even better, the calendar also links to the latest TV-torrents for every episode.
The ajaxy calendar is a very useful tool to track TV-shows. It tells you exactly when the next episode is going to air and if there is a .torrent is available for that episode. The episode data is collected from epguides.com, and the .torrent info comes from tvrss.net, which is another great TV-torrent resource.
Lilx.net seems to be inspired by this other popular TV-calendar. It does not (yet) list as many shows as the calendar at pogdesign, but the .torrent links are definitely a big plus.
The torrents indexed by the calendar are distributed by EZTV and VTV, two well known distribution groups.
