How does one download an SD movie using iTunes? So I have a movie, I would like to download as SD, to save space on my little usb. I go into iTunes, click download and it begins downloading 3.55GB for an hour movie. I'm guessing that is not standard definition. I google some stuff. iTunes > Preferences > Downloads tab > Uncheck Download full-size HD and ensure to check Download high-quality SD videos. ( They were both checked, but okay ). Start download again, yep 3.55GB. Google some more: iTunes > File > Convert > Create iPod or iPhone Version. Except it is all greyed out. Whoever wrote this code should have to purchase 100 movies. Then download each of them to a device other than the device doing the original download. That would be hell enough for anyone.
