    I have 8.1 GB that i have to burn to a DL-DVD....

    I know that it says 8.5 GB on a DL-DVD,
    but sometimes it is less than the advertised amount......

    Can i fit 8.1 GB onto a DL-DVD ?

    I say no. I've been looking at doing some archiving recently and moving away from single layer disks.

    http://en.wikipedia.org/wiki/Dvd#DVD_disc_capacity

    I confess to have not burnt any recent dual layer disks at maximum capacity, however, so take it with a pinch of salt. Toast 9 sets the max. at 7.96GB.

    As an aside, I've always felt companies shouldn't be allowed to say 1GB == 1,000,000 bytes. And "gibibyte", "mebibyte", etc. all sound way too silly to even use.

    is it more accurate to write it in "bytes" than GB's ?

    In actual computing terms, 1GB == 1,073,741,824 bytes. Manufacturers use the SI units of 10^9 instead of 2^30, which is dumb.

    So,

    Am i right when stating that a modern Dual Layer DVD +
    bought at RadioSchack can only hold 7.9 GB ??

    I agree
    It can be very confusing for some noobs….especially when it comes to internet speeds.

    I think I read Snow Leopard reports GB as 10^9 bytes. This could make for interesting issues:

    A: "No, I sent a 2GB file."
    B: "Well, I got 2.1GB. You must have a virus!"

    This has absolutely nothing to do with Internet speeds. You are thinking of the difference between MB (megabyte) vs Mb (megabit) and KB (kilobyte) vs Kb (kilobit).

    Noob. :p
