Just found Aussie Channel Nine FTA on Optus D1.
You can find it here:
Note - DVB-S2 receiver required.
Scan comes up with the name L-Bird1.
Interestingly, programs come through fine, however whenever it goes to a commercial break it blanks out for the duration of the break.
I'm guessing this is a feeder broadcast for regional re-broadcasts, and the regional breakout station would insert their ad's into the blank spots.
PS: Receiving on my 90cm dish, at about 80% signal strength (here in the Tron - city of the future)
