    Ermm... I'll try to clarify this one.
    The laser on the CDR-Drive is either ON or OFF when burning. It also has
    some power rating. To "melt" a digit in the CDR coating it must be present
    in the particular ara for some time. The higher the speed, the less time the
    laser is melting the coating, the less readable the digit.
    By increasing the speed, you are decreasing the signal to noise ratio (SNR)
    of the CD.
    (Its like changing your printer's setting from "high quality" to "draft")

    Old CD drives are less sensitive or with other words require higher SNR.
    Therefore, if you want to read CDs with older drives, burn at lower speed.
    (same with printing: "dont give your grannie a "draft" printout. She cant
    read it coz its too faint.)

    Get some decent burning software from the shop or from kazaa or edonkey.
    I prefer Nero Burning Rom.
