[MEncoder-users] avi to h264 crashing itunes

I'm exploring the best set of options for converting xvid .avi files
to h.264 .mp4 files for an ipod touch.  Command 1 below produces a
file that I can successfully import into itunes, load onto the ipod,
and play.  The file resulting from command 2 plays successfully in vlc
but crashes itunes immediately when I try to import it.

Is anything obviously wrong with #2?  I looked through the mencoder
man page for info about options in #1 (which I copied from the web),
and many of them seemed unnecessary or "use only if you know you need
it".  Apparently at least one of them was needed, but I don't know

Any advice would be appreciated!  Thanks.
