This regex will rename your torrented files (usually associated with RSS feeds, as that is the style used with this expression) to something more human friendly. If using on a *nix os, I've noticed that you have to create all parent directories if using the "rename" script (I have not found any way around this bug).
When using *nix os, I found this simple script to be handy:
rename 's/(.*)\.S(.{2})E(.*).720p.*(?=\.)/\/DIR\/$1\/Season $2\/Episode.$3/gi' *
