Since the resolution of the iPad 2 isn't a retina display, I think DVD rips will play just fine. But now I'm wondering what to do for the iPad 3. For the movies you have on your current iPad, are they HD movies purchased from iTunes or did you convert them yourself? What is the best way to convert? Buy a Blu-ray burner? Do you download the movies off torrents and simply rip them to AAC format?
