Apple Theater Mode Update 2.0Free
Theater Mode is used on some iMacs and on desktop Macintosh systems that have an Apple Studio Display CRT attached (with the Apple Display Connector). It brightens movie playback in some applications like iMovie and QuickTime Player.
This update resolves compatibility issues with the Theater Mode Extension for OS 9, QuickTime Player version 4.1.4 and 5.0, and the Classic environment on OS X. If you have Theater Mode 2.0 through 2.0.2 installed on your OS 9 or Classic OS X system, then you should install this update for best performance and compatibility.
