BTW, does anybody know who to extract basic information about a video from the 
command line? I'm talking about what avidump does with avi files, but 
something that works for most video formats.  For example:

avidump ../videos/911.wtc.2.demolition.closeup.zoomout.avi 
avidump - mpeg4ip version 1.5.0.1
../videos/911.wtc.2.demolition.closeup.zoomout.avi
