Green screen videos on games

[Psygon]

Hi to all,

 

when i play a game, intro videos, appears in green screen

 

 

 

when that video is played with quicktime or orther players, is viewed corrected

also in fullscreen.

 

Is a problem of codecs?

Someone has tell me that is a postprocessing problem. It's possible what I

must do necessarily a new installation of OSX to resolve my problem?
