What are you using to scan for the channels? Myth's own built in  
scanner, or something else? I installed the dvbapps package (IIRC)  
via yum, and used the built-in scan application within that using the  
preset Hanningdon transmitter details, then imported the  
channels.conf that produced into MythTV via its scan GUI.

It may also be worth running the scan at night/early morning when  
it's cool. The heat of the last few days affects DVB signal strength,  
and I'm guessing that could have a negative effect on Myth's scanning  
tolerance?

Hope that helps!
