Hello

Im wondering if my drive can burn dual layer DVDs, it does say dl in this information:

MATSHITA DVD-R UJ-85J:

Firmware Revision: FCQ5
Interconnect: ATAPI
Burn Support: Yes (Apple Shipped/Supported)
Cache: 2048 KB
Reads DVD: Yes
CD-Write: -R, -RW
DVD-Write: -R, -RW, +R, +RW, +R DL

Media: No

So Im wondering if this can burn dual layer DVDs?

sorry if this is a stupid question

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?

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

ho ho ho
