Hello, I bought a Pioneer DVR-109AB for my Mac Pro and I upgraded the Firmware to enable the Double Layer DVD+R DL disc burning. However, I notice that if I leave a DVD or CD in the drive for too long, the drive will spin down and go to sleep... when I go to eject it after, I get an annoying pause for like 10 seconds and the cursor becomes really sluggish and jerky. Then the drive spins up and the disc icon disappears and then reappears again without even ejecting. Then I can go ahead and eject it after all that happens. I was wondering if maybe this is a bug found in the new 1.58 firmware for the DVR-109 and I want to revert back to the original Apple Firmware but, I can't find it anywhere. How do I restore the Apple factory firmware?
