Ok, I counted my chickens too soon.
The program compiles alright,
hr=CoCreateInstance((CLSID_CFrameRateConvertDmo), NULL, CLSCTX_INPROC, IID_IBaseFilter, (void **)&m_pFrameRateBaseFilt);
But the HRESULT return of this is 0x80040154 (Name: REGDB_E_CLASSNOTREG) on a Windows 7 machine.
Any ideas? Thanks!
Kind Regards,
