Ideally of course it would all be free in the UK but if you look at the iPlayer they have to have restrictions on there because of contractual arrangements with the programme makers. It's quite possible that DRM could be used to offer free time-limited downloads through iTunes but you'd have to pay for copies that you can keep just like you do with DVDs. It could be argued that we shouldn't pay for BBC DVDs except for manufacturing and packaging costs but no-one seriously argues that.
Personally I'd like to see the license fee reduced significantly and the number of channels reduced so there's less waste and repeats. Other revenue streams such as downloads can then be used.
