I would then try what filler56789 suggested:
Pull the file on GraphStudioNext window just to check who is taking care of building the graph (or not).
Splitter not firing up ? If no LAV Splitter, then quartz.dll ?
BTW on my system using AvsPmod DirectShowSource decoded that NTSC sample as YUY2,
LWLibavVideoSource (left at defaults) decoded correct as YV411.
YV411 unsupported somewhere on your side ?
You may try to draw the graph manually.

By the way... what are lifted blacks?

This sample contains only few Y values lower than Y=40, even in its darkest parts of the frame (lower letterbox area).
Blacks seem to be centered around Y=40. I would expect a lower limit of Y=16 here.
