Leopard and QuickTime 7.7

Apple today released QuickTime 7.7 for Leopard. This "security fix" will probably break the Media 100i codec the same way that the 10.6.8 system update did. So if you're running Mac OSX 10.5 Leopard and you use the Media 100i codec, I recommend that you avoid QuickTime 7.7 for now.
