dropping frames and wrong frame rate on NASA Thermonuclear Art

[mi3gai4rui4]

Hi, I'm stumped on this and looking for help.

I downloaded the 21.9GB version of the "Thermonuclear Art" movie from here.
Both that web site and MediaInfo say the video is 59.94 FPS.

When I open it with MPC-HC (configured with LAV filters and MadVR) it does not play back smoothly. MadVR's on-screen display shows many dropped frames. It also shows the video frame rate is 25FPS, which is wrong.

When I open it with Windows' built in "Movies and TV" app it plays fine, so I guess there's some software issue somewhere in MPC-HC, LAV, or MadVr.

Things I've tried:
* Updated LAV video filter to latest
* Switched upscaling methods in madVR
* Switched from DXVA2 to D3D11 decoder in LAV Video. When I do this it doesn't play back at all (as in the "play" button in MPC-HC seems to have no effect, the video stays paused).
* Remuxed from .mov to .mkv

LAV Video settings:
Lav Video Decoder 0.74.1
DXVA2 (native)
Active Decoder: avcodec
Codecs for HW Decoding: everything except "H.264 MVC" is checked.

MadVR on-screen display:
Display 25.00005 Hz (8 bit, RGB, full)
Composition rate 25.000 Hz
clock deviation 0.000041%
Smooth motion off
D3D11 fullscreen windowed (10 bit)
h264, 8 bit, 4:2:0 -> NV12, 8 bit, 4:2:0
movie 25.0 fps (says source filter)
movie 3840x2160, 16:9
draw 0,0,3840,2160
touch window from inside

Thanks for any help
