FIX: Original files that are burned to a DVD-RW by using IMAPIv2.0 cannot be changed in Windows 7

Gjelder: Windows 7 EnterpriseWindows 7 Home BasicWindows 7 Home Premium


When you burn data in multisession mode to a DVD-RW by using the Image Mastering API v2.0 (IMAPIv2.0) on a computer that is running Windows 7, the original files that are burned cannot be changed. This is true even though the writing process is complete and all IMAPIv2 objects are released.


This problem occurs because of a handle leak in IMAPIv2 when a multisession writing session occurs for DVD-RW media.
