This is the script I use for running mhegepgsnoop on the rare occasion
I need it (do_mhegepgsnoop.sh):

#!/bin/bash

# DVB-T multiplex frequency (kHz)
DVB_T_FREQ=594000

# Adapter number of DVB-T card.
ADAPTER=2

# Output file to store the xmltv EPG data.
TEMP_FILE=/tmp/xmltv.xml
OUTPUT_FILE=/var/www/epg/listings-mheg5.xml

PWD=`pwd`

if [ -e "$TEMP_FILE" ] && [ -f "$TEMP_FILE" ] ; then
    rm "$TEMP_FILE"
fi

# Get the MHEG5 EPG data from the DVT-T multiplex.
dvbtune -f $DVB_T_FREQ -qam 64 -gi 16 -cr 3_4 -bw 8 -tm 8 -m -c
$ADAPTER 2>&1 &
DVBTUNE_PID=$!
sleep 1
echo Running mhegepgsnoop.py now
mhegepgsnoop.py -v -zp -d /dev/dvb/adapter${ADAPTER}/demux0 -o
$TEMP_FILE
if [ $? -ne 0 ]; then
    rm $TEMP_FILE
    echo Error: mhegepgsnoop failed!
else
    # Temporary fix for bad <channel id> values in the MHEG5 EPG data.
    sed -f /usr/local/bin/mhegepgsnoop_sed_replacements --in-place
$TEMP_FILE

    mv $TEMP_FILE $OUTPUT_FILE
    chmod a+rw $OUTPUT_FILE
fi
kill $DVBTUNE_PID


and the mhegepgsnoop_sed_replacements file contains:

s/comedy-central.sky.co.nz/tvcentral.freeviewnz.tv/g
s/.sky.co.nz/.freeviewnz.tv/g


The problem that was fixing is likely long gone now - I have not
touched this code since April 2014.

Watch out for word wraps, or download the file from my web server:

I am using a modified version of mhegepgsnoop-0.5.2.py - I needed to
ensure that only the DVB-T channels in my database were used for
channel matching, not the DVB-S ones:

root at mypvr:/usr/local/bin# diff mhegepgsnoop-0.5.2.py mhegepgsnoop.py

< VERSION = '0.5.2'
