I usually install games from DVD to the console to have best performance and to reduss 'DVD stress'. After the last xbox update, when I launch a game installation (I tried to install two different games) I had on the screnn the message "installation in progress... don't turn off your console.." but the progress still stay on 0%. If I hear the xbox, the DVD unit is not reading. I tried to do the menu command "empty system cache" but the problem persist.
My Xbox is an elite 250 GB, and my games all all original.
I'm sorry for my poor english.
