Has anyone noticed a rescaling issue with 10.5.4 DVD Player and Time Machine? My wife watches DVDs frequently on her MacBook and I have noticed that one minute after Time Machine backs up to our Time Capsule, the DVD exits full screen mode to some random windowed size. Even more recently, she hits apple + F to go back to full screen and it re-scales itself. She has to hit this key command again to go to full screen and it is fine for another hour. Has anyone else had this problem and found a way around it or a way to fix it?
