I've just found that the Quicktime I downloaded with ITunes says that it is indeed version 7.0.2 but when I found another website that offers 7.0.3 by itself and I downloaded it, when I tried to install it it says that a newer version of Quicktime is already installed and the installation of 7.0.3 cannot proceed while the newer version is installed. I tried using the uninstall feature of Quicktime but that didn't work and it's not listed in my Add/Remove program list.
