    You sure can. The bolded bit is DVD+R dual layer. However, it looks like your drive doesn't support dual layer DVD-R disks, so bear that in mind when shopping.

    Ah right yes the - discs, I think there the ones that cant make a unfinished DVD, whereas the + ones can add stuff to an unfinished one later. I think anyway, basically the - ones are not very good anyway for that reason.

    Cheers, glad its got that feature.

    -R and +R can do the same things. It's your drive that can't do it :eek:

    Not sure about that because theres some websites saying the same thing?

    http://www.askdavetaylor.com/whats_the_difference_between_dvdr_dvdr_dvdrw_dvdrw_and_dvdram.html



    "A DVD-R is a write-once format: once you've burned the data onto that DVD platter, the disk is forever frozen with that information."

    So i dont think im the only one that "couldnt be more wrong". Thats not to say Im not, but im not the only one. If its not true I imagine the difference is branding or some sort of hd-dvd blu ray branding format thing going on, otherwise whats the difference?

    Nope. That difference is between DVD-R/DVD+R and DVD-RW/DVD+RW, not between DVD-R and DVD+R.

    DVD-R and DVD+R differ only in some obscure technical details about writing discs, which are just enough to make them incompatible with drives supporting only the other format. Same with DVD-RW and DVD+RW.

    Correct.

    The "R" stands for "read" and the "W" stands for "write". The "R" stands for "recordable" and the "RW" stands for "rewritable".

    Not quite. DVD-R officially means "DVD-Recordable" and DVD-RW "DVD-ReWritable".

    Ah right, still the dvd minus discs are not as plentiful when Ive been purchasing online. I get verbatim, so at least thats correct :)

    As I observed earlier, your computer can only burn DVD+R DL disks. DVD-R DL will not work.
