I haven't taken that flight but on a BNE-WLG flight two weeks ago in business on a 737 (that's right!) they gave us personal DVD players and a holder full of QF DVD's with the current movie selection offered in other international business class flights.
In fact, the Qantas website lists
this collection to watch on that flight this month.
So TV or not TV, you'll have plenty of choices to watch. Since the regular enterntainment system doesn't let you rewind/fastforward/pause I felt this was a superior system.
*N.B. The players only play the special airline DVD's so you can't bring along anything and watch it on these players.
