hi,
i have a very confusing problem. i just bought a sony dw-q120a Dvd writer. now, when i try to burn ordinary data(files and folders) on dvd+r media, it can only use 4.7gb. but when i try to burn a dvd movie, it can use upto 8.5 Gb. i’m using Nero . why can’t i always burn 8.5 Gb. what is the problem? can anyone help? thanks in advance.
Welcome to the forum 
8.5 GB can be burned only in dual layer discs.
Probably you need to check nero preferences. The pic I posted is rferred to nero 6, but probably there is a similar option in nero 7.
Setting as automatic should solve your problem
first of all, thanks for ur reply.
8.5 GB can be burned only in dual layer discs.
i think that the media i’m using are dual layer. like i said before, when i try to burn video, it behaves like a 8.5 gb dvd.
i tried your solution, but there was no option for it.
anwyas, thanks for ur help.
Probably this option is already set as automatic, so when you insert a DL disc it shows a scale of 8 gb, but when you insert a single layer disc scale change automatically to 4 gb.
Try to do a test and see if there are differences using a DL and a single layer disc.
DVD+R is still SL, not DL.
Use the nero disc info.
thanks a lot for ur help, guys. my problem seems to be sloved.
