+John King I'd say some rather than a lot. One big problem is the number of Septics who complain about British narrators, apparently they can't understand them, so someone has to pay the additional cost of over-dubbing. A rather sad example is Sir David's excellent docus.
It's a shame that the audio seems to have been intentionally cut out. The previous episodes didn't have this disappointing, and ultimately unviewable problem.
