SYMPTOMS
If you install Quick Time version 1.1 or 2.0 for Windows in Windows, you may experience any of the following problems when you try to play an .MOV (video) file:


 * A white line appears across the center of the screen.
 * Two mouse pointers appear. The second pointer is stationary.
 * Video scenes do not play correctly or do not appear at all.
 * When you are playing a video scene, the display is corrupted when you move the mouse pointer over the video scene.



CAUSE
When you run the Quick Time for Windows (QTW) Setup program, QTW detects the video hardware and tries to program the hardware directly. If you are using a video adapter that uses the S3 chip set, the symptoms listed above can occur.



RESOLUTION
Use any text editor (such as Notepad) to edit the QTW.INI file in the Windows directory. Add the following line to the [Video] section of the file:

Optimize=Driver

If the file has no [Video] section, add the section and the line listed above. The section should look like the following example:

[Video] Optimize=Driver

Save the QTW.INI file and then close it.



MORE INFORMATION
Several games currently on the market use QTW to play video sequences during game play. The symptoms listed above can also occur in these games. The game "Myst," by Broderbund Software, Inc., is one example of a game that uses QTW and will experience problems with the S3 chip set.

The products discussed here are manufactured by vendors independent of Microsoft; we make no warranty, implied or otherwise, regarding these products' performance or reliability.
