hey i have a long oversea flight coming up, do you guys know if the below setup will work? google result is inconclusive, some say it does others say it doesnt.. 1) download itune movie rentals to my macbook pro at home 2) once on the plane, with the internet off, play the downloaded itune movie. Will it play? does it require internet? some of the reports are saying they get error message saying cannot connect to itune store etc... but those are from early 2009. Anyone know for a fact if this works, or not work? thanks!
