Some videos/cutscenes (e.g., the Human Revolution recap video and the Breach intro) will not be translated when first played. To fix this, simply start playing any menu video and press Escape to skip it. For example, from the main menu, click "Extras", then "Deus Ex: Human Revolution - Recap Video," and then press Escape. After this is done, all videos should be correctly translated for the remainder of the game session. Note that the bug will return when the game is restarted.
