New Zealand is using DVB-T compressed using H.264.

As a comparison, the UK and Australia use DVB-T with MPEG2. Parts of Europe
however have also switched to using H.264 (e.g. Norway).
Currently Media Center (even the version in Vista) does not support H.264
for TV broadcasts AT ALL! Microsoft currently are very, very poor at
supporting DVB standards.
They also do not currently support
DVB subtitles,
DVB teletext,
DVB electronic program guide,
The ability to receive two (or more) channels from the same DVB multiplex
via a single tuner AT THE SAME TIME,
They also do not support DVB-C (for cable), DVB-S (for satellite), or DVB-S2
(for HDTV over satellite),
Nor do they support MHEG5, used for interactive services over DVB (often
called 'the Red Button')
Some Microsoft representatives have suggested that nearly all of the above
_should_ be added (along with H.264 support) to the next Media Center update
which has the codename of 'Fiji'. This however has been delayed and
currently (being optimistic) would now not be expect until towards the end
of this year at the earliest.
PS. The UK is thinking of moving to DVB-T2 with H.264 however DVB-T2 is not
yet finished so this is still several years away.
