How do I determine the version of DirectX that is running on my computer?
You can determine the DirectX version installed on your computer by using the DirectX diagnostic tool in:
Start->Programs->Accessories->System tools->System information->Tools->DirectX diagnostics
The DirectX diagnostic tool gives a list of all DirectX files and their versions and has some audio video test features.
In case of earlier version of DirectX (Version 6.0 and before), the DirectX diagnostic tools may not be available. This means that you need to upgrade your computer with a recent version of DirectX. To work properly, neoDVDstandard requires DirectX 8.1.
Note: Windows XP Home and Windows XP Professional come preloaded with DirectX 8.1.
