  Perhaps you can use the cygwin just-in-time debugging ability to solve the
problem; that way the program will run as usual, without the debugger
attached, up to the point when the error occurs; then cygwin will attach the
debugger once the error has happened.  Hopefully that means the initial
stages of running the program will be undisturbed and the error will not be
masked.

  To make this work, add 'error_start=C:\cygwin\bin\gdb.exe' (or whatever
else is the win32 path to gdb.exe, according to where you installed cygwin)
to your $CYGWIN environment variable before you start a cygwin shell, then
run mencoder.  Hopefully as soon as it crashes cygwin will attach teh
debugger for you.


    cheers,
