I have as yet not rented a movie, brand new ATV joining in the update fiasco!
I note that you have successfully watched a downloaded movie.
Did you stream it direct or download it to iTunes and watch it at your convenience?
My broadband connection isn't the fastest, so I would prefer to download it.
Any tip to prevent to prevent "This film has been authorised to play on another device" or somesuch would be appreciated.
Here in Ireland, I think I have 48 hours to watch it again, and quite an appreciable length of time for the initial viewing.
Thank you,
Tom
