There does not appear to be a medium in the drive, even though there
is a DVD in the drive that the laptop recognizes and plays just fine.
Same thing happens in /dev/sr1. fdisk -l fails on both.
I did notice that the drive tries to read the disk 3 or 4 times before
it gives up.
I can easily believe that this is a DRM issue, but there must be a way
around it - the DVDs sold commercially in the US are designed to be
playable. If it can play in one computer, it should be playable in
any. I'd hate to think that I have two defective optical burners when
they work to read and burn every other DVD I have.
