I don't know what a strong signal looks like to be honest!

TZAP reports "signal" of around 3333 right now (10pm at night).  "ber" is
sometimes zero on BBC ONE, but usually 0, 1, or 2 on most channels

Is this a strong signal?

Perhaps this is where my problem lies - the antenna is a standard
in-the-loft terrestrial aerial and comes down from the roof to a
splitter/booster box which then splits the signal to the main tv and the
bedroom where the DVB card is currently.  I haven't tuned the aerial for DVB
it is just a standard terrestrial aerial which I inherited years ago when I
bought the house...

Thanks all
