[mythtvnz] TVNZ SportExtra guide data?

[Wade Maxfield]

OK, so with the switch to horizontal, I've updated all my channels 
and now have a pretty standard Freeview setup.  I'm copying my normal 
guide data from the Sky lineup channels so that all the descriptions 
and timings are are exactly the same.

But how do I get data for SportExtra?  I've tried tuning to 
SportExtra then running epgsnoop, but that only seems to find data 
for 1, 2 or Maori TV...

Is there any data for SportExtra to be found?
