SYMPTOMS
When you try to play back certain ASF files created by hardware devices, you may receive an error message approximately 3 or 4 minutes after playback has started.

CAUSE
When applications built on the Windows Media Format play back files, the applications make certain checks to determine if a packet is valid. The Windows Media Format incorrectly handles a case where the time wraps around because of the maximum value possible for numeric data types.

RESOLUTION
A fix is available for download from Microsoft.
