Go to Sky news and then interactive. Remove card (do not put it back in upside down). Then go to TV guide and wait a moment and this will give you the UK epg.
Very little to be gained though apart from ITV 2, 3 & 4 + BBC 3 and 4 etc. Basically just the channels you would store in your "other channels"
Not permanent as such and as you said its basically just the equivalent to going through the menu. They will stay there as long as you have the card out of the box or you turn the set off obviously but you wont be able to receive RTE, TV3 etc. when doing this as they are on the Irish EPG only.Sorry, but I dont understand this - does it mean that when you do this these channels are added permanently so you dont have to go to "services - Other Channels ...." or is it just the equivalent of doing this ?
