I posted this in another thread, but I think this might be the place that people look for it. If you're using the 3.0 version of the OS, smplayer is in Chinese.(Well, mine was in Chinese):
Open /home/user/.config/smplayer/smplayer.ini with leafpad.
Change language=zh_CN to language=en_US or whatever version of English you prefer. It's about 3/4 of the way down, under the [gui] section. Restart smplayer if it's running.
Voila, as the French say: Anglais!
