Ahh... Using analog cable, right?

You are almost certainly using the wrong frequency allocations for  
your cable system. The possible systems are standard, IRC and HRC,  
and the usual symptom of getting this wrong is problems with channels  
5 and 6.

Make sure you have the correct channel lineup selected with  
Datadirect, and that you have properly imported the channels in  
mythtvsetup, IOTW that you have got the channel list from your  
provider (I forget the exact language used).

I think you need to have xmltv installed in order to use that method  
of importing icons. There is an alternative method, using the  
master_iconmap.xml file included in the "contrib" directory with the  
source tarball that is described at:
