Ok, I've tried with everything up to fs=10m cdrecord --dev=0,0,0 --speed=6 --fs=10m --data isofile and I'm still getting the same output I am burning from an iso file created with mkisofs, so I don't think it's that. When you say my disks can't keep up, do you mean the blank media, or my hard drives? I am using 4.3-RC and I remember seeing something about poor disk performance in 4.3-BETA...
