I remember being able to do this before but I just set a new system up and I can't figure this out. When I go to open a file like a mov it defaults to QTX. So right click, open with, select QT7, check always open with but it only sets it for that one file only. I know there's a way so I don't need to do this all the time right? I hate QTX. Nevermind I remembered I guess I just needed to make a post about it to jog my memory lol!
