Thanks Las.  That's a verty helpful suggestion, though for me personally it 
won't help.  (I know that a lot of people like to get information from 
videos.  I don't.  I'd rather read--then I can use my eyes to find the 
places that I want to focus on--except when information is better conveyed 
through motion.  That means that I miss out on some information, 
sometimes.  Each person has to choose how to use her/his time.)
