I'd recommend trying a booster, even living so close. I'm a long way
from the Sutton Coldfield transmitter and need boosters (one in the
loft with the digital aerial before being distributed, and one on the
wall outlet to get decent reception on all channels.

I've also noticed not all DVB cards are created equal in terms of
tuning - my 90002 Nova-T card seems to be much more affected by a
weaker signal than my 2 V-Stream Xpert cards - they also seems to tune
quicker.
