Cross-posting to multiple lists is bad. Posting one big giant blob of
rambling text with practially no paragraph breaks is also bad. Dozens
of lines of appologizing for asking a question, before you get to the
point, is unnecessary... or at least overkill.

Different values for -mc and -autosync are what you need to try. See
the man page.

A limitation of AVI, not mplayer. Use ODML for files over 2GBs.

a/v sync isn't magic pixie dust. You can't add an option to turn on
perfect sync.
Perhaps others here are, but I'm certainly not psychic, and can't guess
what command-lines you have or haven't tried, what messages mencoder is
spitting out which may give a clue as to the problem, etc. I'm not even
sure what platform you're running mencoder on; you make numerous
references to using mplayer on both Windows and Linux.
And last but not least, you should always try latest CVS before
reporting problems, to see if a newer commit has perhaps fixed your
problem.
