MFT_Grayscale.dll call to DllRegisterServer failed

I am trying to build the MFT_Grayscale sample project. I simply copied the project from the SDK tree into my personal code development tree and made no changes to the code. It compiles fine however when I try to register the built dll with regsvr32.exe I get the following error message:

The module "C:\code32\vista\MFT_Grayscale...\MFT_Grayscale.dll" was loaded but the call to DllRegisterServer failed with error code 0x80070005.

I am using Vista Beta 2 and Vista SDK beta 2 with Visual Studio 2005.

Does anyone have any suggestions?

Thanks,
Mark
