I don't have TV in motion in the front, but I did want to let the kids use it on the RSE (my bizarre, autistic 8-year-old son wants to watch the news on the way to school in the morning
).
As far as I know, the DVB I have is factory fitted. Everything else seems fine, so perhaps it really is just crappy reception. Is there any mileage in replacing the aerial or the receiver, or is it just not worth it?
