Screw you, media companies and Apple Computer, for devising ways of making your product suck the fun and convenience out of digital media. Yesterday, I showed an Episode of 30 Days at church. I bought it a month ago, and it worked fine then. But yesterday, since I was in a room with no Wi-Fi, and I hadn't upgraded to QT 7.13, it refused to play until I went downstairs, logged into the iTunes store, and downloaded a 50mb upgrade which was needed to undo the crippling that iTunes 7 had brought with it.
Copyright law and FCC regulation should change but they won't. All the more reason, I supose, to avoid corporate media entirely.
