SYMPTOMS
After you start a computer where the video adapter has the TV tuner or video capture feature, the computer may generate the following error message on a blue screen:

STOP: 0x000000CE (0xHEXNUM1, 0xHEXNUM2, 0xHEXNUM3, 0xHEXNUM4) in DXAPI.SYS

&quot;DRIVER_UNLOADED_WITHOUT_CANCELLING_PENDING_OPERATIONS&quot;

0xHEXNUM1, memory referenced

0xHEXNUM2, value 0 = read operation, 1 = write operation

0xHEXNUM3, If non-zero, the instruction address which referenced the bad memory address.

0xHEXNUM4 N/A

The four parameters within the parentheses vary, depending on the configuration of the system.



CAUSE
This issue can occur if a Windows 2000 version of a device driver replaces the Windows XP version of the device driver. This replacement can happen without your knowledge if you install DVD or TV tuner software or programs from an older CD-ROM that installs drivers that are not designed for Windows XP.

This issue has been documented to occur with the ATI Technologies and the 3dfx Voodoo 3500 device drivers and could also occur with other video cards.



WORKAROUND
To work around this issue, reinstall updated DirectX device drivers that are designed to work with Windows XP.

If the Windows XP CD-ROM does not include device drivers for your device, look for updated drivers on the Microsoft Windows Update Web site. If updated drivers are not yet available there, look on the device manufacturer's Web site, or contact the manufacturer by phone to ask about updated drivers.
