Sacred Rivers.
It is a computer query because its on my hard drive.
I downloaded Sacred River with Simon Reeve Part 3 The Yangzte on to my BBC Iplayer. Everything is fine but at 44minutes the location changes to Nanjing. He walks to a viewing platform and looks across a bridge over the river. The traffic is fairly dense but it is driving on the left hand side of the road a la UK. Fifteen seconds later the is another shot of the bridge and, magically, they have changed sides.
I know it is an editing problem but can you reverse the output or recording from a TV camera unintentionally? Maybe the person doing it thought that all traffic in the world drove on the left. Some people think they all drive on the right.
