Seen it dozens of times on other Macs, it churns for a bit, then spits it out. DVD-R, DVD+R, blank or not, CD-R, blank or not, Leopard installer DVD...
It's a Pioneer drive in my G5, the original as far as I can tell, for the past six months or so I've had its' power supply splitter with a splitter cable for to provide the extra power needed for my GPU. Optical drive still worked fine after that.
Anyways, the only disc it *did* recognise was once of those bristled laser head cleaning ones, it shows up as an Audio CD, DVD Player said it couldn't detect readable media, VLC gets stuck on track 8 out of the 9, 8 being the cleaning track. No errors showed up before that, and the first track, which were the audio instructions, played in VLC fine. Using Sound Studio, opening with any of the .aiff files on the disc gives a "x.aiff" cannot be opened error.
