I bought Automatic after a 2 week trial. I have it downloading on 15 minute intervals from tvtorrents.com (from the UK, while I'm US), based on my "New Favorites" custom account RSS feed. I specify some words to match a show's title, get the format I want (match ".mp4") and exclude ones I don't. (Don't match "720p", don't match "mkv".) The torrents get downloaded to a directory, where Transmission automatically detects and starts downloading them.
The result: Shows appear in Air Video on my iPad, and I only press an entry in a list (Table View) to watch them. My "karma" (called gigacredits) on tvtorrents.com basically takes care of itself because I start downloading when a bunch of other people are also doing so.
That said, TVTorrents.com is a bit clunky. (Along the lines of "2003 called. Wants its Java app server and web design back.")
