As CD/DVD drives and media ages, what you noted does happen. This is why I try duplicating that OS9 install media onto fresh media with a newer drive (something under 2 years old). Then I try that copy. If that fails I swap in a new DVDRW drive into the machine.
There are a few saves by cleaning the CD/DVD lens so always try that before replacing the drive.
