Having watched the first episode of "Silent Witness - Shadows" on Thurs 28 Jan, I went to watch the second Friday 29 Jan on Saturday morning. Started watching but interrupted. When I went back later to watch it, I found it was only available HD. I don't have HD. Has anyone else had the same problem? Why should a programme, which was available, be removed? I can find it on iPlayer on my computer but can not get it via either catch up TV or iPlayer on my Virgin cable service. Can anyone out there help? Can you find it? Will I have to watch it on my computer?
