I have learnt a lesson.SO I want to share as it frustrated me for a
the whole evening.The imported MOV files worked fine for my premiere
pro project but when I reinstalled windows and forgot to reinstall
Quicktime, these imported MOV files only showed a red frame, I
reinstalled Quicktime 2.1 and they would run fine if run from Windows
Explorer but still not in the Premiere Pro project.Then I installed
Quicktime 6.5 and the problem was solved. Lesson learnet- Install the
Latest Quicktime you Have prefereably 6.5 or later.
