I want to use the EPG provided by the TV network - however my TV is configured to use Philips internet based EPG, this is just too slow to use. How can I set my TV to pick up the TV network provided one?

I have the latest firmware, if I plug out the network cable it says it cannot connect to the server or something and says if I want to use the EPG provided by the network then to change the preferences under Home > Installation > Preferences > XXX.

However there is nothing under Home > Installation > Preferences that allows me to change the EPG settings.

I have tried resetting to factory defaults in the settings menu - makes no difference.
