In mythtv-setup for your capture card there is a place to put an 
external channel changer for use with s-video/composite input because 
you need to have some way to change the channel on the external tuner.  
Just put a program that returns true like /bin/true and Myth will 
happily go about it's business and stop trying to change channels on a 
tuner that doesn't exist.
