"Godot" is pronounced "GOD-o" not "Guh-DOE" (and certainly not "God-dot"). Who ever told you it was "Guh-DOE" is incorrect, although it's probably not their fault. Pretty much the entirety of America pronounces it that way, for some reason.
Anyway, please, please, correct your director, correct your teacher, correct EVERYONE who pronounces it incorrectly! Samuel Beckett is rolling in his grave!
