The content of some DVDs cannot be read by Windows 7 or by Windows Server 2008 R2

Applies to: Windows 7Windows Server 2008 R2Windows 7 Service Pack 1 More

Symptoms


Consider the following scenario:
  • You use a Windows XP-based computer to write data to a DVD.
  • You do not finalize the DVD.
  • You try to read the DVD on a Windows 7-based or Windows Server 2008 R2-based computer.
In this scenario, the data may not be visible.

Cause


This issue occurs because the DVD is missing internal session data. This causes Windows 7 and Windows Server 2008 R2 to treat the DVD as invalid.
