Currently, none of the screencasts in the first screencast page are in English, but it's often hard to tell that they are in languages that I don't understand.
I think it's great that you've got multinational screencasts, but some sort of language filter would be nice. Perhaps a dropdown on the page that defaults to 'all', but allows the user to select a specific filter?
