Apple has released its first update to its new Front Row application.

"The Front Row Update delivers overall improved reliability and compatibility for browsing music, photos, and videos on your iMac."
Early reports have shown that the update checks whether the application is running on an iMac G5 or not but it is unknown what it does if it tries to run on another machine.
[Update 1] A reader of World of Apple has confirmed that FrontRow can no longer be installed on non iSight iMac G5's or any other Mac except the new iMac G5.
