Ugh, that is depressing. I suspect that, if you could afford it, if Doctor Who was all you cared about from that BBC channel, you would be better off downloading from iTunes. I don't know how expensive the channel is though... but at least with iTunes you can watch it how much you want, whenever you want.

And given it's on PayTV as opposed to free networks (like Lost and Grey's are, I think?) - that explains why they wouldn't have a free option. Well, there's always bittorrent if you don't mind the illegal option?
