There is nothing "obvious" with software (unless one knows it is an
extremely dumb software).

You logic assumes knowledge of details of interaction (and
not-interaction) of parts of mencoder (alternative explanation is just
lack of imagination on your part, but I prefer the first one ;-).

E.g., mencoder could inform XviD of the current offset into the output
file, and XVID could take this into account when writing its log.

It is much easier to write this down explicitly in the docs than
continue this discussion of "logic".  ;-)
