For US, UK, use both of FS,FSC. If you would like to be a proffessional, choose one of three: movies, series, games. For Tv shows, you should join private tracker which reqiures an invite. Otherwise, you will fail, as I did. Because, for TV shows, one that posts first takes the bigger slice of cake. Look at WBB, you see a nick ,HRA , in Tv shows. Also, you should be awake when USA tv shows are released ( I cant because I am on GMT+2. it means it is the middle of night in Turkey)
It is a though decision.
