I created a 4 second clip and Windows 10 default app gives me error code 0xc00d36c4 - file format may be unsupported, file extension may be incorrect, or file may be corrupted.

Attempting to play with MPCHC or WMP gives me the results in attached pic when jumping through the video.

If I had to guess, I would say the reason for this issue is the odd width/height of the video, that either is not written correctly by MAME (which I doubt) or cannot be read by the player. The most video players don't support an odd video resolution, maybe FFplay is capable.
