According to this post over at Cable Forum, ITV HD is "testing" in the Dundee area. Interesting.
Incidentally, anyone else agree with me that this season of Torchwood is a big improvement from season one? Three episodes now and they've all been top drawer in my book. I was also pleasantly surprised by how watchable the Monty Don Around the World in 80 Gardens was - I tuned in at the insistence of Mrs Nialli (who has greener fingers than me) and found it a thoroughly pleasant way of spending my Sunday evening, infinitely better than the Larkside soap/sitcom and positively eye-popping in HD.
