I'm using some dual layer dvd's to burn for the first time however Nero Vision isn't recognising this ans still thinks that it has a capcity of 4.7 GB and not 8.5 GB.
You change the size in Recode to DVD-9 instead of the default of DVD-5 when you are doing D/L blank media. I would suggest a better D/L program for you to use and it is ImgBurn. Way better than Nero for doing D/L and it is free
Where Nero is reading 7.45 gig, could this be the amount of disk space to be used? Is the 7.45 gig in the Total Size box? If so, the size is the amount of space to be used on the disk.
