when i try this the code below in my project a get link error "[Linker 
Error] Error: Unresolved external '_CLSID_VideoMixingRenderer9' referenced 
from c:\xxxxxxx\xxx.obj"
but i use other guids from the file.
Whats my problem?

hr = CoCreateInstance(CLSID_VideoMixingRenderer9, 0, CLSCTX_INPROC_SERVER, 
IID_IBaseFilter, (void**) &pVmr);

working code (guid from the same file)

hr = CoCreateInstance(CLSID_FilterGraph, NULL, CLSCTX_INPROC_SERVER, 
IID_IGraphBuilder, (void **) &pGraph);

Just a guess: Since the CLSID_VideoMixingRenderer9 is from DirectX9, it 
could be missing from the lib file if BDS doesn't ship with the Dx9 lib 
files.
You could try to define this GUID yourself in your code and see if it 
works.

GUID CLSID_VideoMixingRenderer9  = {0x51b4abf3, 0x748f, 0x4e3b, 0xa2, 
0x76, 0xc8, 0x28, 0x33, 0x0e, 0x92, 0x6a};
