Strength 98%
Quality 100%
OK I beg to disagree with your assessment that those levels are fine. I would say a signal strength of 98% is quite possibly too high and could be causing tuner saturation. I would suggest you experiment by either reducing gain if you have a variable gain amplifier or inserting a variable attenuator into the aerial feed to the Humax and aim for a signal strength of about 80% and see if this fixes your problem.
