i know i can force mpc hc to play it in 185:100
but why is the ratio not correct detected ?

The container also has an aspect ratio value. That one is used by default (when available) because that is in most cases the correct value when it differs from the video AR.

LAV Video decoder has an option for adjusting this behavior. It is called "Use Stream Aspect Ratio".

oki thx
