I had this problem a few weeks ago. It would pause everytime I paged 
down or up. I looked at the backend logs and it would try 5 times with a 
second or so between attempts to load the channel icon if it could not 
access it. I had lost my channel icons when I upgraded to fc2 and 
changed drives but the database still had channel icons assigned for 
about half my channels. Myth will pause / try 5 times to load an icon 
even if it does not exist. I don't know why it just fails the first time 
when it cannot open the channel icon jpg. I found the icons on my 
Misterhouse setup and put them in the channels directory in the mythtv 
home directory and it works great now. If this is your problem you can 
clear out the channel icon settings in your database, download the 
channel icons, or try to fix the code to not try so many times to load 
the channel icon if it does not exist.
