Buggy QuickTime 7.1.5 update (update)
I commented on the QuickTime 7.1.5 update, and how it broke VLC (and maybe other things).
Well it turned out that part of the problem was partly 40cm from the keyboard – deleting the VLC settings (program is provided in the DMG), solved the problem with VLC. And last week Apple released an update for QuickTime.
It now looks like everything is working again….
