Run mythtv-setup and set up new source/input connection and scan for channels using the new tuner
In Channel Editor:
Edit each channel so that XMLTV ID matches the Channel ID’s in freeview.xml
Find out what the sourceid is for the new tuner:
mysql -p -u mythtv mythconverg
enter password
mysql> select * from videosource;
my sourceid values are 1 and 2
Run mythfilldatabase --file --sourceid 2 --xmlfile freeview.xml --manual
existing channels should be found – accept all defaults
Edit script file getxmltv.sh to include this line:
mythfilldatabase --file --sourceid 2 --xmlfile tvguide.xml --only-update-guide
