In NZ our DVB-T freeview [1] is based on h.264 video and he-aac and/or
ac3 audio. It is unencrypted. Any DVB-T card will receive it, and it
can be played without any form of decryption.

That doesn't mean it is easy to play back. H.264 video is far more
processor intensive than MPEG-2, and the linux (read ffmpeg) support
for PAFF interlacing and he-aac is there now, but not in mythtv-0.21.
There are hacked versions of myth [1] that will play this stuff fine,
either with or without vdpau. However without vdpau you are going to
need a machine far gruntier than your present minimum specs on mpeg2.
Also XvMC is not going to help like it can on MPEG-2.

So I suspect what the announcement is saying is "your digital tv with
mpeg-2 codec in it won't play this stuff".

But unless they mean encyption is coming, myth should be able to
handle it, albeit with an upgrade to your CPU or your video card,
along with the "hacked" versions of 0.21.

[1] there is also an SD service running basically the same channels
from satellite over DVB-S via MPEG-2 video.
