We used to have 2 x V+HD recordable boxes and a basic Samsung box.
Then replaced one with a Tivo and had a V+HD, Tivo and the old Samsung box (still 3 in total). At installation time engineer apparently said bill will go down by £7 as the "HD" charge can come off, which it did.
Got a new HD telly so replaced the old Samsung with a Cisco VHD box, understand the £20 charge, but no movies or sports HD channels appeared. Phoned up and told it is £7 per month, got it activated, but is this correct ?
