MacFixIt.com, Apple confirms the problem on Power Mac G4 computers with a CD-RW drive and warns users to “only use CD-RW discs that are rated from 1x to 4x speed. The CD-RW drive in your computer cannot write to high-speed CD-RW discs (4x to 10x speed). Although the drive cannot write to high-speed CD-RW discs, it can read them.”
