    DMA works fine

            IF YOU DON'T USE IDE-SCSI

    Don't use it. Please. There's no point.

    It's much more readable to do

            cdrecord dev=/dev/hdc

    than it is to do some stupid "scan SCSI devices" + "dev=0,1,0" or similar
    totally incomprehensible crap that doesn't even work right.

    Faster as in "it uses DMA for everything, so you can actually burn at full
    speed without having to worry about it or sucking up CPU".
