I have a flat panel iMac with a SuperDrive. My dad recently purchased a DVD+R/VCR unit and has been dubbing our home movies over. However, I'd like to edit some of these with iMovie. Alas, my SuperDrive is a DVD-R only model, and I'd like to replace it with a new DVD+R DL if possible. I took my iMac apart last night and the drive is a standard ATA drive, and the front panel of the drive has been removed. The tray looks to be thinner than the DVD+R DL I have in my PC, so I didn't try swapping them. Has anyone ever replaced a flat panel iMac's SuperDrive or Combo Drive? Which model did you use?
