It does a really great job on those DVDs with strong copy guard, but I had kinda thought it would block any weird digital codes that RCN may be inserting to the blanking bar that may be affecting the Tvs

Please explain how you are feeding RF through a copyguard remover - I thought they typically have baseband inputs and outputs.
