I watched a couple of GP's last year when I was out in Jo'burg.
They take the ITV feed but show it without ad breaks.
It's quite funny when ITV goes for a break, Brundle and co stop talking for about 30 seconds while the ITV ident is showing in the UK, then start again.
Two to three minures later they stop for thiry seconds and then give a roundup of what you've just seen..
