--- Comment #16 from legluondunet@free.fr legluondunet@free.fr --- tokktokk you don't need to install codecs to see the videos on Wine. What Warcraft III version are you using? Could you reinstall the game on a new wineprefix without install third software (no codec or other dll) just the last game version from battle.net.
