It appears that firmware 2.50 also added one other feature, meant to help PS3 owners that are trying to troubleshoot their system. A recovery menu (pictured above) gives users access to a variety of restore features. It will even allow users to install a new firmware update, should anything go wrong during the installation process. To access the menu, you must hold down the power button to turn on the PS3 until you hear three beeps. Then the menu will show up.
DivX and VC-1 (WMV) have been added to the types of files that can be played.
