TheRenamer works for movies, but it's in an counter-intuitive way. I was flummoxed by this as well, since it works differently for TV shows: You have to have each movie in a folder, and it uses the folder name to rename the folder and file within it. That's what I remember, at least.
Sickbeard looks amazing for newsgrup users, but I am using torrents so I gues it`s not for me then.
Sickbeard has limited torrent support. I haven't used it so I can't comment on how effective it is at keeping up to date, but it is there.
All I need is a program that monitors a given folder and then rename the content in that folder and move it to the right folder.
Sickbeard can do that too. It supports a black hole (watch folder) where your torrent client (or anything else for that matter) can just dump a file to and SickBeard will pick it up and process it. I do this with my setup and it works fine. It's not processed "real time" instantly as soon as the file gets there, but if you automate the process it's done soon enough. If you need it sooner, Sickbeard also has a manual process option to force it to run sooner.
