In your IceTV My Account>TV Guide setup do you have only one of Seven - Brisbane, Seven - Central and Seven - QLD with a tick in the checkbox? Similarly for 7mate and 7mate on Prime, SC10 QLD and Ten Digital, and Nine Digital and WIN Television QLD?
I've had similar problems when I had an incorrect setup for this in the ACT guide.
Are you getting any warning triangles for the News recordings on your IceTV My Week page?
