I live next to a road and every time a car goes by I get a slight freeze on my box.It comes back a few seconds later.This seems to me an irritation more than a buffering problem; theirs a noticeable difference. Could this be caused by people using their mobile phones?G4 interference.Is their anything I can do?This happened to me on ordinary TV and I just bought a new amplifier and it stopped instantaneously.Anyone with a similar problem I would like to ear how you overcame it.Thanks
