Hi. I've been away for a while but last I checked. it was recomended to uninstall QT. I have checked the article here:http://avid.force.com/pkb/articles/en_US/How_To/QuickTime-Support-and-Security-on-Windows.
This is from a few months back, I can't seem to find any more info and I am not sure if there is another solution, perhaps included in the latest install files.
Thanks!
