SYMPTOMS
When you are using DirectDraw YUV surfaces, the Matrox Millennium video adapter sometimes erroneously displays bright blue pixels after the conversion to RGB space. This is most likely to occur when you are playing ActiveMovie videos.



CAUSE
This behavior is caused by a hardware saturation problem that occurs during the conversion.



RESOLUTION
You can work around this problem in ActiveMovie by clicking the Advanced tab in the ActiveMovie Control Properties dialog box, clicking Properties, clicking the DirectDraw tab, and then disabling the YUV Offscreen option.

NOTE: The resolution setting is NOT in the retail product.
