    marketing at its finest... the 4.7GB are marketing Giga Bytes -
    with a base of
    1000 rather than 1024. Some people us GiB to indicate that they
    really mean
    1024 base. For GB to GiB you have roughly - 7.5% difference.

    4.7 GB / 1024 / 1024 / 1024 * 1000 * 1000 * 1000 = 4.38 GiB

    You'll see the same with virtually all storage devices - including
    harddisks.
    Read the specs for your harddisk and then check with fdisk or
    something like
    that how big it really is :-)


I don't know whether it applies to DVDs or K3b, but when using cdrecord to make CDs, you can use the '-overburn' option to squeeze a bit more on the disk, more than your actual 4.38GB perhaps.
