I think we're talking on different levels here.

It would be entirely possible to ask the question "is 30000/1001 equal
to 30?" in a context which has nothing whatsoever to do with MEncoder,
or indeed with video encoding at all. (In almost any mathematical forum,
the answer would immediately be "no".)

It is entirely possible to ask the question "does MEncoder drop frames
while encoding?" in a context which has nothing whatsoever to do with
either 30000/1001 or 30, e.g. when going from 25fps to 12.5fps or vice
versa.

Since each question can be asked and answered completely irrespective of
the answer to the other, they are therefore completely unrelated. Q.E.D.
