From: Aleksoid <aleksoid1...@mail.ru>
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.
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.
As a result, we could give VC1_VLD2010 a higher priority and initialize
it first.
