OK, Videofan3D has released a new beta with a fixed FrimSource. He wants to integrate the new Intel libraries before releasing it officially, but I have tested the 32-bit DLL and it works as expected. So, if you want to test it too, or if you prefer FrimSource rather than DGMvcSource, you can
download the package, extract FRIMSource32.dll, rename it FRIMSource.dll, and overwrite the original DLL in the BD3D2MK3D's toolset folder.
I will release the new version of BD3D2MK3D when the final version of FRIMSource will be available...
