Is there some reason you're using -mc 1?  I would first try without
"-mc" at all.  If that doesn't help, try different values for -mc.
0/0.01/0.1/10.

You can also try using the binary DLL instead of ffmpeg by adding "-vfm
qtvideo" to your command-line.

And as always, you should try a CVS snapshot to see if the problem has
already been fixed.

Attentive reading of the man page will certainly tell you all of this. 
The HTML documentation isn't explicit about it, but reading through it
should still give you a good idea how it works.

RANT:  I've never understood why so many people expect just changing the
file extension will work.  In my many years of experience using numerous
programs, I can only recall a handful that will actually change the type
based on the filename extension (sox/convert/ffmpeg).  Absolutely
everything else in the world requires you to set a filetype option
somewhere.
