You need the CVS dvbtune I think (and therefore modules which
implement the new dvb api) in order to set the correct error
correction flags for each multiplex. This is the script I use to scan
the Oxford transmitter (my local one):

#!/bin/sh
# Scan the UK DVB-T broadcasts from the Oxford transmitter
#
# USAGE: ./scan_ok-t.sh > channels.xml
#        ../xml2vdr channels.xml > channels.conf
#
# See http://www.linuxstb.org/dvb-t/ for instructions on how to find
# the frequencies for your local transmitter.
#
# If you are a DVB-T user outside the UK, you will need to amend tune.c
# with the detailed tuning parameters for your country.

# NOTE: CHANGE CARD TO SUIT YOUR SYSTEM - FIRST CARD IS "0", SECOND IS "1" etc

DVBTUNE=../dvbtune
