I came across something strange while letting madVR upscale a cute little 240p movie to 4k resolution. Please have a look at the following output:

luma -> NGU Sharp (very high) 4x -> Jinc AR

As I understand it the NGU sharp algorithm is applied 4 times and on the third round my little 240p movie should have a height above 2160 pixels. At this point downscaling is quite an interesting part. Why in the name of this planet is Jinc afterwards applied and no downscaling? I think I'm a little bit too stupid to get it.
EDIT: I have also a second question. Isn't it possible to apply pixel shaders while using D3D11 copy-back decoding? mpc-hc says it can't use pre or post resize pixel shaders and I simply don't know why.
