sorry for the disturbance, it looks like a "bug" in MPC :D
I think first DXVA specs said that we need to use raster order, or
didn't said anything at all about the order, I don't have the first
specs to check.
one flag (Reserved16Bits) is used to specified the specs rev to use,
we just need to update it in MPC and remove the hack.
you might also be interested to know that in MPC we use Reserved16Bits
= 0x534c for Intel cards, I don't know why I'll have to ask the main
dev who worked with an Intel engineer to make it works.
