Regarding my previous post about the new Front Row in Leopard, it is possible to actually revert to the old version. Just replace the Front Row.app in System/Library/CoreServices with the Front Row.app from Tiger (from a Tiger install DVD or some other source you can find). Then restart. Of course, you should back up the original Front Row.app just in case things don’t work as desired, or you just suddenly decide that you like having music interrupted each time you go in or out of Front Row. Or you watch all movies that are not rentals or video podcasts all in one go. If you like that kind of pain, why would you even revert then?
As for me, I am a happy camper again. Back on the old Front Row, complete with cool transition from desktop.
