Since this is container specific, it seems more likely to be a bug in LAV than in madVR, don't you agree?

IDK, but with other renderers video work just fine.

It seems problem caused from "smooth motion" and occur only if smooth motion is enabled and set to "always" or "... or if the display..."

The video has messed up timestamps. Smooth motion tries to reproduce the timestamps as exactly as possible. Here's an example of the timestamps for a couple of frames:

2412.81 -> 2413
2414.79 -> 2415
2416.79 -> 2417
2418.78 -> 2419
2420.79 -> 2421
2422.78 -> 2422
2422.78 -> 2423
2426.79 -> 2427
2428.79 -> 2429
2430.79 -> 2431
2432.79 -> 2432
2432.79 -> 2433
2436.79 -> 2437
2438.79 -> 2439
2440.79 -> 2441
2442.79 -> 2443
2444.79 -> 2445
2446.79 -> 2447
2448.80 -> 2448
2448.80 -> 2449

As you can see, the video file often asks 2 frames to be shown at the same timestamp. This is responsible to the problem.
