Can't burn .iso to DVD+R with dvdrecord



I have an OEM BenQ DW1620a in my Linux server since I thought it would be a cheap backup device. Also, these drives are dirt cheap and I have another one that works really well so what the heck.

Anyway, I have an iso I’m trying to burn (I’m making backups of the install discs for my new laptop) and I can’t get it to write. It’s driving me crazy. dvdrecord says that the disc is too small, and that I’d have to overburn. Well, the file is about 1 gigabyte in size and it’s a blank DVD+R, so there’s lots of space.

I think I read somewhere once that DVDs like to be burned to at least a gig so I wonder if that’s the problem. Maybe this is a nudge too small.

This is with Debian Sarge. I don’t have KDE or Gnome installed since it’s a server so I’m stuck with the command line.
