Any clues on where I should look for this? > Whether you are using cdrecord or burncd or whatnot, you're sending MMC-class SCSI commands to the burner to do the work. cdrecord is much more sophisticated in how it does this than burncd (hence why ATAPICAM is needed and not the canned ioctls that stock ATA provides to burncd), so it's likely that your drive has some sort of quirk that burncd can't cope with. Probably the best way to get this fixed is provide access to the hardware to Soeren. Barring that, atapicam + burncd is a fine replacement. I'm not sure what you mean by 'opening the entire bus', though. Scott
