using dvbtune I get a "Signal" strength around 12500 to 13000 and "Verror"
of either zero on BBC 1 or perhaps either zero or "1" on ITV. Block errors
are constantly on zero at the moment and I only get the occasionaly audio
glitch (loud squeek) perhaps once a week or so.
This seems to be quite strong? I am near Wimbledon and probably about 10-15
miles from the Crystal Palace transmitter (which is pretty tall...).
That's a perfect signal to me. Maybe one of the transmitters you tune to is
completely broken or do they all come from Crystal Palace?
