One thing I find unusual about the mythtranscode version is that when 
you specify to "--honorcutlist" or -l, it expects you to pass the 
cutlist on the command line if you specify an input file instead of a 
chanid and starttime.  This behavior seems unintuitive (although I can 
see why someone would want to pass a cutlist on the command line). 

I would think that passing a cutlist on the command line should override 
the use of the one in the database, but the cutlist should be loaded 
from the DB is --honorcutlist is used and no cutlist is passed on the 
command line.  Maybe I'm thinking about it the wrong way, but that would be:
