Multimedia Tuner Extension: Red Check Mark Through Icon

When I start up my Macintosh PowerBook 540c and my extensions appear across the bottom of the display, there is an extension with a red check mark over the icon.

I know that a red *X* over an icon means that the extension did not load for some reason. What does a red check mark mean?
The Apple Multimedia Tuner 2.0.1 extension starts up with a red check mark over the icon. This is the normal appearance of Multimedia Tuner icon.

The Multimedia Tuner addressed some performance issues which occurred with some multimedia applications when used with versions of QuickTime previous to 2.1. You should update to QuickTime 2.1 or newer, which includes the fixes in the Multimedia Tuner. QuickTime software can be found at:
