QuickTime Player won't play movie bought from iTunes Store.
Finder's Quick Look says that QT Player can play it. QT Player says to first authorize through iTunes. iTunes says that it's already authorized.
I've seen the same problem in various places all over the net but it just started happening to me with 10.8.3. Never had a problem in 10.8.2 or earlier. Any ideas on how to fix?
