People, I've been told my iMovie HD issues in Snow Lep may be caused by not having Quicktime 7 any longer. I previously had the Quicktime 7-Pro version, but that got removed and replaced by Quicktime X when I upgraded from Tiger to Snow Lep. I went to the Apple site to download Quicktime 7, but I'm getting a message in the install process that says "This version of QuickTime 7 can't be installed on this disk because QuickTime X is already present". How can I get Quicktime 7 back on??? and still preserve Quicktime X too??
