growisofs
I've been burning DVDs with the aid of genisoimage and wodim. This usually looks like the following:
genisoimage -J -r . > ~/tmp/dvd.iso
wodim -v dev=/dev/dvdrw1 ~/tmp/dvd.iso
Today, I went to burn my first dual-layer disc, and found that wodim wasn't up to the task. I'm not sure why, but in my googling I found someone mention that wodim was having a problem burning dual-layer, gave an error message that looked a lot like mine, and said that growisofs was able to do the task just fine.
So I gave it a test. growisofs apparently combines both the mkisofs/genisoimage and the burning task in one. It looks like this:
growisofs -dvd-compat -Z /dev/dvdrw1 -dvd-video ./
This one was a DVD-Video disc, hence the -dvd-compat and -dvd-video options. Sure enough, it burned just fine. So, someday when you try to burn a dual-layer disc, if wodim chokes on you, try growisofs.

I haven't tried a dual layer disc. Should it look like the old laser discs of the past? Thanks.

No, they're only one-sided and the same size as a regular disc. Many movies on DVD, especially the ones with longer movies or more special features, are on dual-layer discs.
