    Zarlink Semiconductor has introduced the first commercially available
    laser diode drivers that support x16 DVD and x52 CD write/rewrite
    speeds for the next generation of optical disc drives used in
    high-speed DVD/CD combination recorder units.

    DVD/CD recorder units will be able to write a 4.7 Gigabyte DVD disc –
    the equivalent of a two-hour movie – in under six minutes. In
    comparison, it currently takes an unacceptable 1.3 hours to write the
    same movie at x1 speeds.

  2. Nobody is using 1 x speed these days.
    It is now 2 or 4.

    Nobody will use Zarlink parts if they keep spamming us like this.

    how can it take 1.3 hours to write a two hour movie at x1 speed?

    Because x1 doesn't mean what you think it means. It is kinda like in WWI, they
    didn't refer to it as 'one' at the time. (Exception, "History of the World,
    Part I", directed by Mel Brooks). DVD recorders just came to the market at some
    writing speed and now that speed is refered to as x1.

    At least I think this is right.

    I think it actually refers to the base read speed in the first recorders.
