The BBC is discouraged from producing its own content, so a lot of the content is made by third parties and the BBC doesn't have the rights to broadcast them outside the UK. That's why you get BBC branded channels in different countries because those channels have to compete to buy the rights. There's lots of other things too, like music rights, sports rights etc. Means the content has to be redone.
