with tv pack the epg data is over the air but you can change it to use the downloaded guide data. i had a problem with itv1 only showing now and next
I am not near my machine now so i can't exactly remember where the setting is but you can add a epg listing to a channel so you could add a itv1 channel to itv1 and it will use downloaded epg data instead of over the air data. This fixed it for me
