    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

    artifacts resulting from compression perhaps?

    Are these high-definition files by any chance?

    The image attached is from a dvd that I downloaded.

    But this is also happening when playing small files video files in my safari browser?

    Do you think it has something to do with the logic board?

    From what you said, I really think it's just the quality of the files. If it happens in online videos, maybe give us a link so that we can test to see if we get those kinds of colors too.

    If other people don't have that problem, then yes, it is a problem with your machine. If others do, it's just a bad file.

    Check it on other machines.

    maybe its the particular codecs you have? i'm just guessing. It can very much be a software issue.
