Burning a dual layer DVD using Nero

Hello Geeks.

I've got a 7+ gig .iso of a Linux distro that I'd like to burn to DVD. I would assume that since the file is pretty big, that I'd need to burn a dual layer DVD. Problem is, I don't know how to do that.

I am using Nero 6 Reloaded. But when I try to burn the .iso the program says that the file is too big for a single DVD. However, the program doesn't give me the option of burning the .iso as a dual layer. Is this normal? Or is there something I'm missing?

Thanks for your help.

 

What's the nero version you use?
Nero version 6.6.0.13 supports dual layer, try an update

 

Thanks for your replies.

I'm using Nero 6.6.014, so it's up to date. It's the Demo version right now, haven't received my activation code yet. Could that be a problem?

Also, Halo, my burner supports dual layer DVD-R and DVD+R. So, that's cool.

I just couldn't figure out where in the burn process I can choose the "dual layer" option. Maybe it's cause it's still the demo version. I don't know.
