For those of you, like me, who want to download current episodes of TV shows there is a great program to do this automatically.
TED
http://www.ted.nu/It's very customizable and already has pre-programmed filters for common shows. You can also filter results based on wildcards or keywords so that you can DL only episodes from certain "distributors". It's based off of RSS feeds which you can also add your own feeds if there is someplace other than the normal sites it provides.
Also, it doesn't download the files itself. It just DL's the torrent file and uses your client of choice.
