PS you can buy TVs in NZ that will tune and play the h.264 channels,
but I'd be pissed if I was an Aussie and had bought a TV with only a
MPEG-2 tuner to be told it won't work any more.
I have seen TV's advertised in NZ at different price points depending
whether they have the digital tuner in there. I suspect they can
therefore be added as an "extra", but YMMV.
