This issue may occur if third-party DVD movie players or DVD disc creating programs, such as InterVideo Launcher or Nero 7 interfere with the reading of the Flight Simulator X disks. The DVD discs for Flight Simulator X are formatted as Universal Disk Format (UDF) Volumes. Typically this kind of DVD disc is read by a UDF volume reader that is installed with Microsoft Windows.
