For me - 5750 UVD2.2 - it's not working even though DXVA checker says about the Device decoders:
"ModeH264_VLD_NoFGT: DXVA2, 720x480 / 1280x720 / 1920x1080 / 3840x2160"
"ModeH264_VLD_NoFGT_Flash: DXVA2, 720x480 / 1280x720 / 1920x1080 / 3840x2160"
So from the side of hardware and driver, UVD 2.2 is capable of 4K x 2K and if CoreAVC DXVA is capable of 4K x 2K, as it is clearly seen by your screenshots, then the problem must be an artificial restriction in everything else but VP5 inside the code of CoreAVC DXVA.
DXVA checker reports for clips beyond 1080p and CoreAVC DXVA the following:
"ModeUnknown (NV12): DXVA1 (VMR)"
and of course it's not working.

Do you have access on VP5 hardware or could someone else from your forum post some benchmark results for clips 1 to 10 or at least 7 to 10 ?
