Ah, you're right.  I compiled the dvd+rw-tools myself, and the default
`gmake install' installs the programs with the setuid bit set.  I saw
what I thought was a reference to my bug on the freebsd-ports-bugs
list [1], so I thought this problem occurred in the ports collection
as well.

It turns out the FreeBSD port installs the dvd+rw-tools with mode 555
and the problem doesn't reveal itself in this configuration.  However,
if you do set the setuid bit on the programs built from the ports
collection [2], you get the behavior I described.  My little patch
fixes that.

[2]  I don't know, is there a particular reason why the dvd+rw-tools
     should or shouldn't be installed that way?
