    Original movie DVD's seems to be app. 7-8 gigs. A DVD record for home use is
    app. 4.7 gigs.

    What kind of DVD format/record is the original DVD's?

    What's the difference between these two?

    Cheers

    Many, but not all, commercial DVDs are dual-layer and hold twice as much
    data as single-layer recordable discs.

    Go to www.dvdrhelp.com and read one or two of the guides on copying DVDs and
    you'll see there are several solutions to this apparent problem. DVD Shrink
    is one.

    So, you seem to think that dual layer DVDs are a problem.....

    commercial dvds are pressed and can hold up to 18gig(4.7gig per layer per
    side). You burn in the dye layer on the dvds you make at home, and
    currently the technology is single layer per side.

    The format of the original is "pressed" and it is 2 layers, unlike the 4.7gb
    disc which has 1 layer. Another name this "pressed" format is called is
    DVD-ROM (technical bit setting on the disc). You'll often hear it refered
    to as simply "original" "source" or "retail." Another word which fits is
    "legal."

    The 2 layer (dual layer) disc actually holds 9.4gb, its just studios usually
    only use 7-8gb.

    BTW, it is is a good thing to note that the 4.7 & 9.4gb refers to
    1,000,000,000 bytes, not a true Gigabyte. A real Gigabyte has 1,073,741,824
    bytes. As you can see, that causes some problems. You can actually only
    have a 4.38GB folder to burn onto a DVD±R disc, so if you have a folder that
    Windows tells you is 4.70GB, it won't fit by a longshot.
