The BBC has decided it can do without an HD channel just to showcase its gorgeous nature documentaries. As such, it's turning BBC HD into a high-definition simulcast of BBC Two, starting March 26th. As it's already been doing that job for a while now, it's hardly surprising -- but does make us wonder where HD shows from BBC Three and Four will be housed in the future. The corporation did tell us that it's evaluating adding more HD channels, but we don't imagine that'll be happening in the near future. BBC Two HD will remain on the same channel as BBC HD, Sky: 169, Virgin: 187, Freesat: 109, Freeview: 102 -- so you don't need to rescan your box to keep watching Eggheads.
