It never used to do this, but recently Quicktime has been taking lengthy amounts of time to load my movie files. When loading, Quicktime would hang and the spinning cursor would spin until eventually the movie would open. It's been doing this since before the past two QT updates as I was hoping they would fix the problem, yet they never. It seems to do it files over 200mb, and I've only tested AVI files but it could be any other files either. Trying the videos in Front Row, I get the same lengthy wait with a black screen and Macbook fans blaring away. I've recently upgraded to Leopard, hoping this would fix the problem and it hasn't. Any ideas?
