    Which consumes the most battery, a dvd movie played on the 13 in or a movie downloaded on Itunes? I am going on a 9 hr flight and I want to conserve as much as possible.

    Definitely the DVD will consume more, because a DVD will require your DVD drive to spin along with the HDD, where a movie on iTunes will only keep the HDD spinning while the DVD drive is idle (that is, assuming your movie is pre-downloaded and not streaming)

    I haven't done the experiment, but the downloaded movie watched in iTunes will consume far less battery power. Of course you could do the experiment yourself.

    the dvd and the itunes movie both use programs to run and that cancels out. They both use memory so that cancels out

    The dvd needs the superdive to spin up and down as the dvd movie is cached and buffered into memory. That will cause the dvd movie to need more battery.

    I agree the DVD will use more power. However, also bear in mind that watching any movie will considerably decrease your battery life.

    Battery and DVD

    I figured as much but just wasn't sure. I have the 100 watt Hypermac battery to use with the 13 in MBP so I should be OK. Thanks.

    Reducing the screen brightness will help a lot as well.

    Just rip the dvd to the drive and you are set. Skip itunes.
