I installed the 8.6 upgrade on my B&W G3-400, and can no longer run DVD movies with the DVDPlayer app. Instead, I get an error: Apple DVD Player cannot open because the Apple CD/DVD extension is not istalled or the DVD-ROM Module could not be found.
The extension is installed and enabled, and of course the DVD module is installed. Everything worked great with 8.5.1.
Has anyone else encountered this problem?
