Basics of what I have set up is:

Tune dvbstream to 1219, grab sky based data to .xml file
Tune dvbstream to 1183, grab freeview based data, and split into 
individual channel files
merge sky based data with sport extra file, import results with 
mythfilldatabase, then reschedule.


My actual script massages the data in a couple of ways, and uploads a 
copy to my web server, so I've trimmed it a bit, just leaving the key 
bits.  You'll no doubt need to tweak this to your setup.


NEWFILE=/tmp/listings_beta-$$.xml

cd /tmp/
# tune to sky transponder
/usr/local/bin/dvbstream -s 22500 -o:/dev/null -f 1219 -p h -n 60 8192 &
sleep 2
/usr/local/bin/epgsnoop > $NEWFILE
killall dvbstream

# wait a bit - since Steve sees overlapping data
sleep 5

# tune to freeview transponder
/usr/local/bin/dvbstream -s 22500 -o:/dev/null -f 1183 -p h -n 60 8192 &
sleep 2
/usr/local/bin/epgsnoop | tv_split --output %channel.xml
killall dvbstream

sleep 2

# merge the data
tv_cat --output /tmp/listings-latest_beta.xml 
/tmp/sportextra.freeview.co.nz.xml \
/tmp/tvnz6.freeview.co.nz.xml $NEWFILE

# and fill the database
mythfilldatabase --no-delete --file 2 -1 /tmp/listings-latest_beta.xml
mythbackend --resched
