Looks like you are right, thats the hashes I get as well.

In any case, I have a working WIP patch that fixes sa10091 and sa20021
with DXVA2, which were broken before.
I'll clean it up tomorrow and send it for testing.

Unfortunately I don't have a sample for field mode with slices, so
that remains un-implemented. If someone comes across such a thing,
that would be nice to have.
