    I don't know exactly when this happened - either it was when I upgraded to 10.4.1, 10.4.2, or when I installed the recent security updates, but my DVD-RAM drive (factory with my 450mhz G4) will no longer read my burnt DVD-Rs. All other DVDs work just fine, including my retail DVDs (like for Tiger) and movie DVDs. This is a major problem for me because I like to backup all my DVD disks (data - like Tiger, not movies) and then use the copy instead of the master (much less wear and tear on my masters). I also have a lot of backed up data on DVD-Rs and if I can't read them then how will I restore? I tested all of my burnt DVD-Rs on my work computer and they are fine, and they all read on my 450mhz G4 before a few weeks ago when I installed 10.4.1 or 10.4.2 or the recent security updates - not sure because I haven't used any of them since then. I saw a note somewhere on the internet about someone having problems with creating a bootable DVD from a disk image in 10.4.2, but it didn't really pertain to this issue. I know all my DVD-Rs are good. Final note, the disk goes into the drive, it spins and makes a bit of noise, the hard drive crunches for a second and then the disk spits out, every time! I've tried seven different disks that I know work, and are even bootable. Does anybody have a clue as to what this problem is?

    I know it sounds like a broken wheel, but you didn't mention it, so I'm going to say it anyway. :D

    Have you repaired permissions? This is actually conceivably something that could be the result of permissions, and OS X has a history of permissions issues with the volume files that deal with optical media (like on Panther, where the CD iso file would get its permission repaired every single time you did repair permissions).

    First thing I tried, no luck. I tried it again just because, still no luck.
