I'm another who's recently dropped sky in favour of freeview. I have the Panasonic 550gz. I have noticed I am getting picture dropouts for a second or two at a time while watching freeview HD. When the picture drops the sound is still working. I've checked the signal strength and condition on the tuner and they are both at max strength on every channel. I am wondering though because the coax is very old, and the UHF aerial on the roof is very old and rusty. Is this likely to be a signal issue if they tuner reports full signal and quality?
