    I'm trying to understand how fast a DVD burns, I mean in minutes it takes to burn data to the disk. What I want to burn to DVD is actually just data for storage, not movies.

    Let's say I want to burn 4.7 Gigabytes of data to a DVD. The way I calculate it, if I burn at 2.4x, it should take about 27 minutes to do this, once the burn is started.

    Is that about right?

    By the way, I don't own a burner... yet.

    That is an impressive 115 pages of text; however, I can't fathom how someone could compile that much information and not one word about how long it takes to write one DVD--at least there is no mention of it in the sectioin titles.

    [4.3.7] How long does DVD recording take?
    The time it takes to burn a DVD depends on the speed of the recorder and the amount of data. Playing time of the video may have little to do with recording time, since a half hour at high data rates can take more space than an hour at low data rates. A 2x recorder, running at 22 Mbps, can write a full 4.7G DVD in about 30 minutes. A 4x recorder can do it in about 15 minutes.

    Note that the -R/RW format often writes a full lead-out to the diameter required by the DVD spec, so small amounts of data (like a very short video clip) may take the same amount of time as large amounts.

    Thanks for the pointer; with such a long document, I missed it.
