 About VC1_D2010.

 > The VC1_D2010 profile, also known as VC1_VLD2010, has the same
 functionality and specification as the VC1_D profile. Support for this
 profile serves only as a positive indication that the accelerator has been
 designed with awareness of the modifications specified in the August 2010
 version of this specification.
 >
 > The following GUID is defined for this profile.
 > DEFINE_GUID(DXVA_ModeVC1_D2010,0x1b81beA4,
 > 0xa0c7,0x11d3,0xb9,0x84,0x00,0xc0,0x4f,0x2e,0x73,0xc5);
 >
 > Hardware accelerator drivers that expose support for this profile must
 not also expose the previously specified VC1_D GUID, unless the
 accelerator works properly with existing software decoders that use VC1_D
 and that do not incorporate the corrections added to the August 2010
 version of this specification.

 I think what this means is that VC1_D2010 (and all other synonyms for
 DXVA2, D3D11, D3D12) should be given higher priority than VC1_D.
