Here are some screen shots taken with MPlayer dev-SVN-r25017-4.1.3 built a
couple of days ago.

I get a frame and then mplayer crashes

I also have an additional HD TVNZ stream.

Now the 1080i streams are a little odd as they are native 1:1 1920x1080i
whilst in Europe they tend to transmit 16:9 flagged 1440x1080i.

Also I've heard that at the moment the test streams are actually being
generated on a PC rather than using the production encoders.
