“There are many new and exciting features in all of the DirectX components. The SDK has added a new member to its core technology called Managed DirectX, a DirectPlay port for the PocketPC, a High Level Shader Language for D3DX, and Windows XP parity on downlevel operating systems for DirectShow and the DirectX audio APIs. DirectShow also has a new Video Mixing Renderer (VMR9) which uses D3D9 surfaces and always renders video through the 3D pipeline, along with new and exciting samples. The generic Windows Media Format SDK stub library (wmstub.lib) available in previous beta releases has been removed. DirectShow samples using this stub library have been reverted to the DirectX 8.1 behavior of displaying a warning to obtain the stub separately, and the readme.txt files have also been reverted with information on the process to obtain the stub.
