This article was previously published under Q122131



SYMPTOMS
When you are using a Diamond VideoStar video capture board and the Diamond video driver version 1.02, Microsoft Video for Windows fails to capture frames and then displays the following incorrect error message:

Confirm that vertical sync interrupts are configured and enabled.



CAUSE
The Diamond VideoStar board works with Video for Windows unless Video for Windows is in preview video mode. This limitation is not mentioned in the Diamond VideoStar documentation.



WORKAROUND
In Video for Windows, switch to a view other than preview video mode before you capture a frame.



MORE INFORMATION
Below is a list of other potential problems with the VideoStar card that although documented by Diamond may affect the operation of Video for Windows.


 * The switch settings for the port address of the daughter board (which enables video capture functionality) are mislabeled on the VideoStar card itself. You can find the correct settings in an insert supplied with the VideoStar documentation.
 * You must run the Diamond Video Snooper utility in the background while Video for Windows is running. If Video Snooper is not running, a "capture device not detected" error message is displayed.
 * Be sure to follow the instructions in your Diamond documentation regarding maximum screen refresh rates. Most modern computers default to faster refresh rates than the VideoStar supports. If the refresh rate exceeds that supported by the VideoStar card, screen corruption may occur in Windows.

For more information, contact Diamond technical support.

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