G5 Dual 2.0 (running 10.4.7) with a new Dual Pioneer DVR-111D drive won't see blank disc media. I have the latest firmware for the device. It will recognize burnt media, CDs, DVDs and such but won't see a blank disc thats popped in. HELP PLEASE!! Do not know what to do. Is it a further firmware update, a software update is it the media I am using, a preference somewhere?
