When you use My Computer to preview a video or still image, you receive:

Video Preview Failure
Creation of the video preview failed.
Please check the device connection and make sure that the device is not being used by another application or user.

If you unplug and reconnect the imaging device, without closing My Computer, you may experience this behavior.

To workaround this behavior, close and re-open My Computer. In some cases, you may have to restart Windows XP.

NOTE: When you unplug and reconnect your imaging device, the Windows Image Acquisition (WIA) service may incorrectly report that the device is not connected (to Camocx.dll, the WIA Camera View DLL).
