QuickTime's been broken for me for some time. I can't play .mov files and I can't render SFM movies in any decent format. I'm getting really tired of this and I want to remove every single file that's related to QuickTime, with codecs and all that. I've tried re-installing it but it just won't work. I'm suspecting the codecs for it are broken or something, I got a virus some time ago that messed up a lot of things, and I'm guessing QT is one of them.
So, any tips on how to do this?
