Installing the Windows Region Change Support Components

Application developers can utilize the DVD region change support built into Windows to change region inside the DVD playback applications. There are two different ways of doing this for the Windows 9x and Windows 2000 platforms.

  • Under Windows 9x

    Under Windows 9x platforms, the region-change application, DVDRgn.exe, is installed only when a hardware decoder with a WDM stream class minidriver is installed using the standard INF file. For other software decoders and the upgrade market, insert the following lines into an INF file used by an installation program to add DVDRgn.exe to the target system.

    [Version]

Signature=$CHICAGO$ LayoutFile=layout.inf

[DestinationDirs] DvdRgnCopy=25 ; Windows DefaultDestDir=25 ; Windows

[DefaultInstall] CopyFiles=DvdRgnCopy

[DvdRgnCopy] dvdrgn.exe

  • Under Windows 2000
    On Windows 2000 systems the component that provides the DVD region change support is in the DLL storprop.dll (available in %windir%\system32). This DLL is installed by default and no extra steps are required to ensure that this DLL is available.
