I know there are posts already on this, but I cant find one specially related to my question. Which is, Ill be traveling this week and Ive read that battery life can be maximized if I watch a dvd right off the HD as opposed to running the disk on my superdrive. Do I have to download ripping software, or is there a way to upload it to iTunes? Or do you all think Ill be ok watching a three hour movie on my nearly brand new macbook 2.2? One thing I hated about my old computer was the battery didnt hold its charge after two years and movies would quit right at the best part! Thanks all!
