I have a Powerbook G4 15" Aluminum 1.5Ghz, had it for nearly 5 years now.
As of late when playing video files the screen does not display the video correctly, green patches start to appear in certain areas of the screen. This only happens when playing certain video files (wmv, .mpg), but for some reason when playing .avi or dvds the problem does not occur.
Does anybody know why this is happening? Is there any way i can fix this?
I've attached a screenshot showing the problem that occurs.
Any help on the matter would be great
Thanks
