Takes ages to do it - VisualHub could do the job in half the time! But my main complain is the quality of the export. I've played around with the settings, Apple TV preset and the mp4 settings, and they all come out with slightly blocky picture quality. Nothing like the original. I know I'm compressing, but for example, TV shows downloaded by other means, the quality is great and it is at the same bit rate as my exports.
