When you are in the process of setting up and you get to the bit where you're asked for your location, ie postcode, I always avoid giving mine and give someone else's !!!!!!!
The reason being, we live in Weymouth. If I insert our postcode, the regional TV covers the South which although includes us, but stretches up to South/East (Dover area).
We actually prefer to view South/West Region, so by inserting a postcode Plymouth for example, then we automatically receive the area, Isles of Scilly/Cornwall, area's of our choice.
Does this sound odd?, is it something you do. I know it is possible to find all the regional tv stations, but I prefer our area to arrive automatically after National News.
