Yes.

It says:

Disc in /dev/sr0 is a video DVD.

(It says this before I try to open the disc, when it puts the k9copy
application window on the screen.)

Which log(s) in particular? There are a lot of files in that directory.

I imagine that you mean ~/.kde/share/config/K9copy

The only thing in that file that made wonder is that there is a line that says:

dev=

I wondered if it should say:

dev=/dev/sr0

but when I made that change k9copy instantly crashed on startup, so I put it
back the way it was.

Yes. I even made the user (dangerously) a member of every group. Made no
difference: k9copy still wouldn't open /dev/sr0.

My best speculation is that the act of inserting a disc into /dev/sr0 causes
some other program to grab /dev/sr0 in a way that renders it impossible for
k9copy to open the device. But that doesn't make much sense, since other
programs seem to be able to open it OK. I'm completely out of ideas at this point.
