I have a flash drive and i put a movie on it from my friends laptop, when i put it on my laptop it wouldn't play because a required codec isnt available.
What does that mean?! My friends laptop is an acer and mine is a mac is that why it wont work?
It means that QuickTime cannot play it. Download VideoLan for Mac & all your problems will be solved.
