If you would like to FOREVER rid yourself of the "take charge of your whole computer and world" Quicktime, go
here and download "Quicktime Alternative."
From the webpage: "QuickTime Alternative will allow you to play QuickTime files without having to install the official QuickTime Player. All QuickTime formats (.mov, .qt, .3gp) are supported, including streaming content and QuickTime content that is embedded in webpages. Some advantages compared to QuickTime player: quick and easy install; it's easy to make an unattended installation; no background processes; use a player of your own choice; low on resources."
I've used it for several years without problems.
