The solution has already been discussed.  The problem is that ffmpeg's 
argument for the "-b" switch has been changed.  For example, if the old 
command line looked like "ffmpeg -b 4557"  the new line should be 
"ffmpeg -b 4557k".  I am running FC5 and recently (today 20061020) 
updated (using yum).
