For those who want to add a torrentcast to their bittorrent client, the link is http://www.mininova.org/rss.xml?user=PodcastPing
Poke around in the menus and you should find where it goes under something for RSS. If you don't find anything, then your client doesn't support it. The latest version of (m)uTorrent does.
For those with uTorrent, go to "Options" "RSS Downloader" and under the "Feeds" tab click on the "Add" button at the bottom. This will bring up a menu. Enter http://www.mininova.org/rss.xml?user=PodcastPing for the requested feed. Now when you go to "Options" "RSS Downloader" and click on the "Releases" tab, you will see a list of all releases, including any new ones. Click on the release to open the torrent for download.
