QuickTime Alternative will allow you to play
QuickTime files (.mov, .qt and other extensions) without having to install
QuickTime Player from Apple. It also supports QuickTime content that is embedded in webpages. The very user-friendly installation is fully customizable, which means that you can install only those components that you want.
The
QuickTime Alternative iTunes add-on allows you to use QuickTime Alternative or QT Lite together with iTunes 8. Without this add-on iTunes will give an error about missing components.
