I currently have two lcd tv's both with built in freeview. They are both connected to an old TV aerial via a signal booster in the loft. Problem with the main TV is that the picture will freeze just for a few seconds, this happens now and again and happens on all channels. The second TV, this is a 19 inch which i've just recently set up in the bedroom, Problem I've got with this one is that some freeview channels are missing and poor reception on all bbc channels. itv channel 4 and 5 are fine. Could it possibly be the aerial?
