I am trying to edit some AVI files that came from my video camera which I've copied to my Windows XP computer. I recently upgraded to Quicktime Pro to allow me to edit (cut out part of) the files, but when I try to export back to AVI, I get the above error message and it says "a file could not be found". I am using Quicktime version 7.6.2. I'm only trying to export / save a 2 minute file.
