Interestingly, I tried your way to check the header, and it turned out
to be right!!!

My way to check the dominator was writing a avs script like:

a=directshowsource("encoded.avi")
messageclip(string(a.FramerateNumerator)+" "+string(a.FramerateDenominator))

and then when this avs was played, it showed a message: "52484375
2189038", which means the numerator is 52484375, and the dominator
2189038. Obviously, it is avisynthis that has a bug not mencoder.

Thank you for your advice.
