It uses the same decoding unit as DXVA, but the GPU itself for deinterlacing IIRC.

It doesn't rely on a DXVA compatible renderer and it works fine with up to 16 ref frames. (But 16 ref frames also work fine on DXVA - at least on Vista/7, for pretty much every Nvidia Card and all ATI cards HD4xxx and newer)
