If you look at:
http://www.dtg.org.uk/retailer/dtt_channels.html
you will see that most ITV channels fall into MUX2. Then you use:
http://www.dtg.org.uk/retailer/tx_n.html
(first line of second table) to see that MUX2 = channel 66. Then you use:
http://www.digitalspy.co.uk/terrestrial/tuning/
to determine your frequency (ch 66) is (last column for digital channels) is 834 
MHz. Go to your Transport Editor within the channel editor (in mythtv-setup) to 
see if you are picking up a transport at that frequency.

 From tx_n.html it would appear that all the channels for you are bunched up at 
the high end of the table, and you may get a bit of spill from one channel to an 
adjacent one. If so, someone else may be able to tell you how to tweak your 
reception parameters to reduce crosstalk. I'm lucky (Hannington) that I don't 
(in the main) get such problems.
