Then let me see if I can find it.

Well, I think I have figured some of it out anyway.
I used DVD-R DL, and my DVD player could play the first _half_ of the
disk. Which tells me that it read one layer, but not the other layer.
What bothers me is the movies that use 8GB disks play just fine. When
I saw "double layer", I thought it was the same physical structure
that movies have always used to fit such large files. I guess I was
wrong.
My laptop, with a standard DVD burner, it turns out, cannot read the
DL disk at all. "no recognizable track found". Yet it can read the
large movie disks just fine, so obviously a movie disk uses a
different format from everything else.
Welcome to the world of DRM, ne?
