Apple DVD Player 2.2
Quicktime 5 PR has been installed since the first day of it's release. It's been that long since a DVD movie had been run. When I tried Saturday night it gave an error that the DVD software needed to be installed.
The software from the DVD Player 2.2 was reinstalled.
Original DVD software from OS 9.0.4 Install CD, then the DVD 2.2 software
Deleted Quicktime extensions/programs and preferences, and copied Quicktime 4 extensions/programs and preferences from backup.
Then did a re-install from the OS 9.0.4 Install CD, DVD software and the 2.2 software. This step finally got the movies to work again.
Has anyone else had this problem?
