In other words, what you did wrong was create 2 separate video sources 
for what should have been one video source.  First, 
http://www.gossamer-threads.com/lists/mythtv/users/264034#264034, then 
create a single video source and populate it with /all/ the channels 
(that are available on the, er, source of TV signals that's connected to 
the input of the capture card).  That means your one video source should 
contain radio stations for which you get EIT data and TV channels for 
which you get listings from your XMLTV grabber.
