    Now I see it's a bit more complicated. The label clearly states 1-4x
    speed (an image is at http://www.maxell.eu.com/, unfortunately there
    is no direct link to the web page) but the Maxell's compatibility list
    states that Plextor PX-708A can use 8x speed. New DVD drives, namely
    my Plextor PX-712A, is not listed there. The Plextor's web page
    http://www.plextor.be/technicalservices/technology/recmedia.asp?choice=Supported%20media
    states that Maxell's DVD+R(4X) can be written at the 8x speed. So the
    information provided by dvd+rw-mediainfo was correct. I'll try to
    burn one more DVD+R at the 8x speed.

    Anyway, I'm puzzled where the 8x speed comes from. Is it stored on
    the disc or does the firmware provide the speed? It guess the latter
    is true since some drives can only use the 4x speed.
