Yes, that made things work just fine.  I guess that answers the question 
of did I do something dumb :-)

After the video input file and before the video output file are the same 
place for muxed streams but may be different for separate raw audio and 
video inputs, which I did not consider -Doh!

The  -vf filter being silently ignored in the first case above is what 
confused me. No warning, no error, no mention of it at all as sell as no 
filtering.

Well, Ubuntu 12.04 ships with libav and the "frozen" ffmpeg included 
there did the cropping, but I don't know how it relates to "real" ffmpeg 
1.0+ I build from git.

BTW http://ffmpeg.org/trac/ffmpeg/wiki/UbuntuCompilationGuide was a 
wonderful resource for the build it from current git process.
