Brand new system. Fresh everything. Some MOV files are opening, but some aren't (looks like anything I created in After Effects). I haven't downloaded any QT anything, nor activated the QT plugin in Deprecated Features, because I think that was the cause of some of my previous stability issues in my old machine (or, at least, Magix Tech said it was the QT plugin that was causing it...)
On my old machine, NO MOV files would open without the deprecated QT plugin checked, but some MOV files open now without "doing anything." Do most people still have to activate that in order to play certain MOV files?
