Bought and downloaded Ironman 2 the other day from iTunes and everything went remarkably smooth and fast (1st time buying movie from iTunes). It gave me 3 movies, an HD version, a SD version and iTunes Extras. Why would it give me an SD in addition to HD, if I wanted the SD version I would've bought that instead of HD. Not aggrevated or anything but was just wondering do they give it to you for a more iPhone/iPod friendly format? But my real question is when I access the movie from FrontRow how do I know I am accessing the HD version and not the SD? If I access it through iTunes I can hover over the movie and can then choose between playing the movie or playing the Extras. But if I access it through Home SHaring from my Air it shows me both the HD and SD version to play as well as the Extras.
