When you try to use a packet-writing program for optical media recording devices on a Microsoft Windows XP Service Pack 2 (SP2)-based computer, the program may run slower than expected.
This problem occurs after you install Windows XP SP2. Windows XP SP2 introduced a change in cache management. This change causes write operations to the optical disk to occur nonsequentially.
